Thanks for playing! I'm glad you enjoyed the game. You can find the devlogs on the game's store page just under the download section, though they're mostly just patch notes with some design discussion.

MonoGame is great in terms of the amount of freedom it gives you to make what you want from scratch, but that also means you have to deal with some annoying technical stuff most engines would take care of for you. The default audio API in particular isn't very good, so it's recommended that you use some type of audio middleware.

If you need help getting started, I used GameFromScratch's tutorial series on YouTube. There's also plenty of documentation of the MonoGame website.

Sorry for the late response!

Thanks, I'm glad you enjoyed it!

I'm glad to hear it! Thanks for being patient as I fixed the game; most players wouldn't be so kinds as to submit multiple detailed bug reports. This experience has also been really enlightening. I never considered how foreign language computer settings could affect my game. I suppose this is what I get for using a custom game engine. Thanks again for your help!

Sure thing! Here's how it works:

• The environment is stored as a 2D array of pixel object, which each stores its current color (black pixels are just null, with no pixel object).
• When a blood drop hits a wall or passes over a pixel object in the background, the addColor(Color c) function is called on the pixel at that (x, y) coordinate.
• If the pixel's current color is not c, then its color gets changed to c, thus coloring it in.
• If the pixel's current color is already c, then addColor(Color c) gets called on all adjacent pixels, thus spreading the color.
• (Make sure to use a set of pixels to keep track of the ones you've already visited so you don't visit the same pixels multiple times).
• (You may also want to add a range to the maximum spread distance, or prevent color from spreading upwards depending on your needs).

That's the basic version of how it works. It gets more complicated if you want to add in color mixing like I have in Blood Pressure, but I'll leave that up to you to figure out. I should also mention that this system works well in Blood Pressure because of the simple, monochrome artstyle with a lot of negative space. IDK how well it would work with other artstyles, but feel free to experiment.

I made the engine myself using the MonoGame framework: https://www.monogame.net/

I find that having a custom engine gives me a greater degree of control, and I don't have to hunt down documentation when something goes wrong since it's all my own code. However, it can be pretty difficult building everything from scratch, so it isn't something I'd recommend for everyone.

Okay, thanks for the feedback!

Okay, thanks for the feedback!

Thanks for the feedback. I'm glad you enjoyed the game.

Sorry about the difficulty; balance is something I'm still tweaking.

If you could tell me what you got stuck on and what was giving you the most difficulty, that would help me balance the game.

Thanks again for playing!

You're right! This should be fixed in the version I just uploaded. Sorry for the hassle; I didn't realize that foreign language settings would mess with the in-game text like this.

(BTW, the "controls" menu will still display "?"s for some characters, but it shouldn't crash the game).

Hopefully that's the last of the crashes!

Okay, I figured it out. It's not the Turkish keyboard but rather the Turkish language setting. Apparently, the Turkish language setting on Windows autocorrects all of the lowercase i characters to Turkish ı characters which the game doesn't know how to handle. Since the game displays all text as uppercase anyway, I just manually changed all the text in the game to uppercase. The game shouldn't crash anymore in the version I just uploaded. Thanks for helping me fix this bug!

Ah, that make sense. Thanks for letting me know!

Thanks for the bug report! The Turkish keyboard is definitely the problem; I imagine it has characters not present in the game's font, hence it getting replaced by a "?". I hadn't considered international keyboards. The new version I just uploaded should stop the game from crashing when this happens. Although the character will still be displayed as "?", the game should function as normal. Let me know if it still doesn't work.

Thanks again for your helpful comment!

Okay, thanks for letting me know!

Thanks for playing! I'm glad you're enjoying it. 

Can you clarify what you mean by "this fix doesn't apply to windowed mode"? Is it still crashing for you in windowed mode?

Hey, I just solved the problem! Turns out it specifically happens when setting the jump input to a key which contains lowercase letters, like "Space", since the explosion effect on the main menu wasn't programmed to handle lowercase. The new version I just uploaded should fix this issue.

Thanks for the bug report! After reading your comment, I was finally able to fix the bug! As it turns out, it was being caused by the menu explosion effect when starting the game. If you assign jump to a button with lower case letters like "Space", the explosion effect isn't programmed to handle it. A simple one line fix. The fixed version will up shortly.

Also, thanks for suggesting an  easy mode. That's definitely something I'll be looking at for the full version.

Thanks for your help!

It's tiny, just 5KB, so I doubt storage is the problem. Sorry, I'm really not sure what causes that issue :(

Thanks for the tip, I'll look into it!

Yeah, I'm just saving to the game folder itself, so I guess it might not have permission depending on where you put the folder. Not sure how to get around that :/

Sorry to hear that. I haven't run into this issue myself, so I don't 100% know what's causing it. My guess is that an error is occurring when the game attempts to save, since hitting new game creates a new save file.

Try playing the new version I just uploaded. If I'm right, it should no longer crash, though saving won't work.

Sorry to hear about the save file. I've heard some other people having problems with that, but I'm not sure what causes the issue.  I cannot reproduce the bug on my end, which makes it difficult to fix.

When you go to the game folder, is there a "savedata" file? If so, what does it say inside when you open it with notepad?

Sorry to hear that :(

If you tell me where you were in the game, I can recreate your save and send it to you.

Thanks :)

Thanks for the feedback! I'll check out that bug and see if I can fix it.

Mac and Linux builds are definitely something I want to do for the full release! Unfortunately, I'm a solo dev without access to Mac or Linux machines to build/test on, so they will have to wait for now. I'll let you know if/when builds are available for those systems.

Thanks for the question! The game is made with MonoGame. It's not an engine, but rather a framework which handles assets, inputs, etc. The rest is really just written by me from the ground up. I like it because it gives me a lot of freedom with how I program the game, although it does mean I have to program most of it from scratch.

I actually uploaded one a little while ago on Twitter: https://twitter.com/RedOshal/status/1321617751530635264

I'm glad you like the game! Sorry about the audio issue; I'm still not sure what causes it. The game auto saves, so closing and re-loading should fix it. I'll add that to the list of known bugs on the game's store page.

Thanks for the feedback! I noticed that bug, but I can't consistently reproduce it or figure out the cause. Fortunately, the game auto saves, so you can just close and re-load if you get stuck. Also, the wall will eventually break if you keep shooting at it from different angles. Sorry for the inconvenience! Hopefully I can figure out the solution soon.

Thanks for the question! The game is made with MonoGame, which is basically a modern version of XNA. I like it because it gives me a lot of freedom with how I program the game, although it does mean I have to program most of it from the ground up.

Thanks for the question! Each paintable pixel in the environment is actually its own object. I'm able to optimize it because it's all on a fixed grid, so lookup is really quick. I don't need to update the pixels outside of when they get colored in, and I only draw the pixels that are actually on screen, so it's all O(1). Paintable pixels  on moving objects like platforms and thwomp are a bit more complicated, but follow the same general principal. It also helps that the art style leaves a lot of negative space, meaning there are fewer pixels to keep track of.

A few bugs/issues to report:

During my first playthrough, the game crashed the first time I tries to warp (screenshot with error message below). The gauge on the left of the HUD was in the red zone, so I assume the game just doesn't have a response to trying to warp with a broken engine at that point in the game. The only other thing I did was manually realign the ram scoop at some point as I was messing around with the controls, so that might have something to do with it.

After resetting and playing for about an hour, I ran into another crash which occurred when I tried to place an item to the north of to the power generator in my ship. My only theory on that I somehow managed to place the item inside of the generator, causing the game to crash since that isn't a valid location. Upon trying to load my save, I'm greeted with this crash:

I started a new save, played for a little while, then manually quit to desktop. Coming back later, I received the below crash when trying to load that save. So far, I have not been able to actually load a save outside of the very start of the game:

I also ran into a bug with control rebinding. I rebound the pause button from Esc to Shift so that I could pause the game without moving my hand from the default position. However, this prevents me from capitalizing letters in text fields, as pressing shift immediately exits the text entry.

I also ran into issues with the key rebinding menu. The function a key is bound to would be performed as I am trying to rebind a key, preventing the menu from functioning properly. For instance, let's say I want to rebind move left to the L key. When I press Space to select move left, instead of waiting for my next input, move left is immediately be bound to Space. In other words, using the interact key to select the function I want to rebind immediately binds that function to the interact key I just pressed. This means that the only way for me to use the key rebinding menu is with the mouse. Also, when rebinding the pause function, as soon as I press the new key I want to rebind to, the menu is immediately closed since I just pressed the key which is now bound to pause. Similarly, when rebinding the move left key, the menu selection immediately moves to the left since I just pressed the left button when I rebound the key.

I'm sure others have mentioned this already, but mouse controls are utterly broken on the select save file menu. After selecting a file, the mouse cursor is still able to change files by mousing over them. Also, clicking on the confirm/go back buttons do nothing; you have to use the keyboard to select (although you can still highlight them with the mouse). There also doesn't seem to be a delete save file function.

Also, I found a strange behavior with menu mouse control when entering text. If you have one text field selected and use the mouse to select another text field, the text will be transferred from the first text field to the second. Maybe that's the intended behavior, but it was super unintuitive; I expected selecting the next text field to simply confirm my selection and move onto the next one. You also can't deselect the text field by clicking outside of it with the mouse. Unless I'm missing something, it seems like the only way to deselect a text field is using the keyboard.

This next one isn't a bug, but still an issue. The first time I went to an uninhabited planet, I didn't realize that the layout was randomized every time you go back to your ship. As I was using my oniris device, I ran low on stamina, so I decided to leave it on the surface and go back on my ship to sleep and recover my stamina. It was a bit of a nasty surprise finding that my device had disappeared when I went back down, especially since items are persistent on inhabited planets.

I also wound up missing the deadline for the first cargo shipment of mundanium. I didn't realized what had happened at the time, as the dialog didn't acknowledge that the shipment was late, but the boxes weren't being taken. Having a popup to notify the player of a missed shipment would have helped. You may also want to not have a time limit for the first delivery so that players have some leeway to figure out the systems.

On a related note, I wasn't sure if cycles were passing in real time, or if it only happened when I went to sleep since that's the only time there's obvious feedback for cycles passing. I'm sure I could figure it out by staring at the delivery timer for long enough, but it wasn't clear to me as I was playing for the first time. (Overall, the delivery timer UI a bit hard to gauge, since it doesn't seem to tell you the exact number of cycles remaining).

Finally, as I was writing this comment, I noticed that the game still takes input even when the window isn't focused. Even with the game minimized and my computer focused on my internet browser, I somehow managed to open up a new save file and begin the tutorial as I typed.

Anyway, I really enjoyed when I got to play of the game, especially when I got the warp drive and unlocked the multi-start-system deliveries. I especially enjoyed the item lifting/placing mechanic; moving things around in that sort of embodied way is really satisfying. I hope this issue report helps you create a more polished experience!

Thanks, I'll keep you in mind!

Thanks! I'm a solo dev without access to a Linux machine to build/test on, so not for the time being. But I'm definitely looking at multiple platforms for the full release next year.

Very impressed by the improved moving animation; it makes the game much smoother and easier to control. I wound up buying all of the upgrades and made it to depth level 40.

One issue I did run into one time was the door not spawning in a level. It happened on depth level 20 with the arrangement that has a horizontal band of blocks on the bottom (specifically the variant with groups of 4 gold orbs interspersed). I haven't had this problem on that level before, so I'm not sure what's causing it. Hope this info helps!

Ah, is this the issue you're running into? https://www.addictivetips.com/web/fix-this-file-is-not-commonly-downloaded-and-m...

Just click the drop down arrow, then click "keep."

Hope this helps.

Hey, sorry to hear that you're having trouble running the game. If this is being caused by Windows Defender SmartScreen, here's how to get around it:

First, click the "more info" button on the initial popup:

Then click "run anyway" on the following screen:

If this isn't the issue you're running into, please post screenshots of the message you're getting so I can better understand the issue.

Thanks for playing! Too bad your first video didn't record properly, but I'm glad you liked it. By all means, you can keep the video up (I'll never say no to free publicity, lol). 

Sorry about the lack of full screen support. I didn't realize the max window size would be so small on larger monitors. I was intending on including a full screen mode, but ran into some technical difficulties getting it to resize the game correctly based on the monitor resolution. When I find a fix to the problem, I'll definitely update it. I'll try to get that up in the next few days.

Also, sorry to hear you lost your save. If you tell me where you were in the game, I can actually send you a save file at that point. 

Anyway, thanks again for your video! Your feedback is appreciated.
