itch.io

It’s not properly explained at all. I didn’t have time to implement a much needed onboarding system, unfortunately.

The game uses a supreme commander style flow-based resource system. You can start building as many nodes as you like but each node takes a certain amount of resources per tick to continue building. It’s not an up-front cost. So the enemy spamming buildings isn’t a problem in reality, in fact it’s hurting itself and those buildings are highly vulnerable

The way to beat the game is to cutoff the enemy HQ from any connections. Surround it with disruptor walls and its HP will drain, ending in your victory.

Tbh the game is incredibly tricky to balance and I did a bunch of math to try and come up with workable defaults. But currently being aggressive here with network directionality towards the enemy and disruptor nodes is the winning strategy every time.

I wish I had more time to polish this and explain the mechanics better. A post jam update is planned

Hello, as mentioned below the page is passworded so we cannot see the submission. We have disqualified the game for now but pleae contact us via Discord hen this is resolved

Hello,

We have disqualified this game for now because it doesn’t follow the rules of being 20 seconds long. Is the game bugged in some way? Because I can’t seem to do anything in it.

When you have updated the game in line with the jam theme and rules, please come by the discord and let us know so we can put it back in.

Hi! Thanks for submitting your game to the 20 Second Game Jam!

Unfortunately, the rules of the jam require you to provide a freely playable web version of the game on itch.io. Furthermore, the game is not 20 seconds long.

We can see you effort into the the game so please join us on the discord where someone may be able to help you export a web version of your give you the information you need to be able to create a web version of your game, which is supported by Godot engine.

We made the game invisible in the jam for now. If you are able to modify the game so that it follows the jam rules, we will be happy to put it back in.

You did it– a 20 second puzzle platformer! It works and I had fun. Would have like some sound effects though

Fun concept that indeed “left me wanting more”! Great entry

Thanks for playing!

Being able to push through clouds either by dashing or sheer determination is actually a totally intentional part of the game and it has indeed been balanced around it.

Ah ok, no bugs then it looks correct to me. I’ll take into account that the minimap might be too small for future updates. Nothing is getting cutoff that I can see, did you notice that the world wraps around the x axis? The stuff on the left is actually from the right side of the maze being drawn as “ghosts”. The maze generator will create connections between sides too so it can be useful to take advantage of

Thanks for sharing the screenshot and thanks for playing!

Could you share a screenshot regarding the map being offscreen? Discord preferred but here is OK too if you’re not there.

Regarding the clouds… “that’s not a bug that’s a feature” ;). I probably shouldn’t give that away already because it was meant to be a secret mechanic and I wanted to see how many people discovered it. But maybe it’s OK because the game is actually more fun and much easier when you figure it out. It’s been somewhat balanced for it too as there’s a trade off in speed and vulnerability to birds

All submitted games must include a version that is free and playable in web browsers

This game was DQ’d during the ratings period due to not being made with Dragonruby, which was a rule of the jam.

It’s a solid entry otherwise and worth playing so it’s now returned.

Thank you for this detailed review on all the ways the game sucks. It’s more than it deserves =P

It was created in jest in about an hour as a parody while I worked on my “real” entry. That there aren’t more negative reviews is just because people are too nice

Unfortunately, I couldn’t figure out how to unlock the other balls.

Really interesting from an implementation perspective though. Great physics and FX. The use of signed distance fields with pixel arrays for rendering and logic is quite novel for a DR game

Interesting sound toy. I had fun trying to get everything timed into some kind of rhythm

Fun gameplay with very satisfying animations when you smash though trees, fun sound effects and appealing art. Love it when you can chain time bonuses. Whee!

“Bouncy Swordfights”

Literally exactly what was promised.

First class production values through and though. I laughed while I chopped up the baddies. Great…. everything

Wow, challenging! From the first level I wasn’t sure some of these jumps could even be made. I made it to the upper part of the third level so far.

There were clearly some challenging programming problems solved making this game. Respect

An “auto jumper”! Seems like it should be a genre but first I’ve heard of it =P

Great implementation with some really lovely art

What a great and hilarious concept! It’s quite fun, too. Personally, I’d like the difficulty to scale up a bit faster.

Surprisingly authentic CGA graphics! It’s unusual enough for a jam game that it felt fresh

Wow that’s just one shy of the theoretical maximum which you probably can never get due to the physics sometimes causing new spawns to leave the screen.

You are way too good for this game

Mooooooooo

First, congrats on shipping a tiny game!
Looks like you used BlitzBasic

I was definitely amused by the art and music

I’m sure you’re aware collision detection is a bit glitchy. There’s a few other bugs too, but the game is indeed completable.

Also the game speed seems tied to refresh rate. It ran too fast on my 165hz monitor.

What would be really appreciated is a way to quit the game before the ending without having to kill it in the Task Manager

I also wrote some samples using the impulse-based approach

Simple: Boingy

More advanced, with rotation and better solver Boingy2

The second one is a little messy still because I’ve been busy with other projects and haven’t cleaned it up, but it should still be helpful

Below are links to tutorials that take a deep dive into making things boingy. They are sorted from simple to complex so be prepared for some heavy duty math as you get near the bottom. If you want help with maths stuff, come see us on the DragonRuby Discord and head for the #math-physics channel.

Not speaking for the host, but there is some general guidance on this topic that applies to most game jams.

If you’ve been coding for any length of time you’ll have a library of fairly generic functions you’ve written that apply to multiple projects. Maybe some of those functions were “borrowed” from stackoverflow originally. Some might be fairly large like a grid drawing and querying system or an animation system if the engine doesn’t provide one.

Bringing in the grid or animation systems is typically fine in most jams (not Ludum Dare), but a larger system that also includes character movement, and pre-programmed abilities that is nearly a playable game already, is not.

If it’s code you feel like you have to ask about–don’t do it

Thanks for playing! There are quite a few known bugs as I was unable to work on the game during the last week and had to ship it unfinished. I haven’t seen the scoring issue mentioned but I have a good idea what it might be,

The game is absolutely inspired by Bubble Bobble, good catch! As I continue working in it, I will be bringing more ideas from that game
