this is clearly sonic, and you have done a great job at capturing that feel both with the ost, main design and mechanics.

but i have to say, i'm not a big fan of the overall color palette you went for, but i guess that's subjective

The level design could use some work. The last level was the best one by far. Lots of momentum and the turret enemies added a little bit of spice and you could plow through the level. The stop and go on the collect map was a bit annoying. Also I wish there was a bit more contrast between the ui, player, and background. The character and sound design are great!

This could use some camera hints in the level

Red = Where I want the camera to go
Pink = Where the camera currently goes (violently moving every time I hit a new platform)

Black = Places the camera never needs to see. These could be collision volumes for the Camera, blocking the camera never from straying too far off of the main play area.

Or just zoom out a bunch

-The kerning on the letter 't' is quite bad. Distracting in otherwise good looking visuals.

-Options were a little weird at first, but I eventually got it and it's pretty unique.

-Gameplay is very fluid, I like it. Compared to other games, it feels a lot more like you're controlling a robot vs fleshman with robot skin. That said, I don't particularly like speed platformers.

-Music and SFX are good.

-Second level is neat, how it loops back to the beginning. At this point I'm getting a bit better at the controls, and compared to sonic it seems a bit easier for me to understand what's up ahead. It's also forgiving with the speed boost, since it both slows down time and you can do it mid-air to correct yourself.

-The last level, with the guns, had a small issue where the character was on the far right of the screen. Therefore it was a bit hard to see what was next, though it wasn't much of a problem since it was right at the end.

-Beat in 4'58''. Also when I select exit on main menu it just doesn't, lol(might be a web thing where it auto restarts?).

Looks good, keep it up.

I like that you didn't copy Sonic mechanics 1:1 as these games are wont to do, but, as a result, the controls feel a bit janky and inconsistent. Wall jump inertia is odd, you get insane momentum by jumping on a specific type of slope, sometimes you just bounce off stuff flying into the sky, you can wall jump-dash back onto walls to cheese momentum checks, etc. I think sorting these out to feel good is higher priority than adding content. I got through the available levels and I agree with the sentiment that some spectacle early on would be nice; it might be a good idea to have those machine gun sequences in the first stage. That being said, I disagree that the level design is bad. It's perfectly fine; it's really the controls themselves that are getting in the way.

It was fun and challenging.

I assume Sonic was a big influence here.

What inspired the main character's design?

fun stuff. you clearly have a solid idea of who your target audience is.

the game controls fine and plays as expected. the boost/burst button is a welcome addition.

the main thing i saw that i think is a negative is the level design. i think it's important for the first few levels to have as little "start/stop" design as possible, but to instead allow the player to easily to a "gotta go fast" move, where there's few non-jump skillchecks, so that the player can easily get used to their momentum, speed and capabilities. if the map is hard and the player is new, it will be hard to get a good grasp of the controls/movement, and thus make learning actual challenging levels even harder, due to a lack of established infrastructure. it's not that the levels are too hard, it's that it's too much too soon. spikes and holes are fine, i'm more focusing on the "tunnel" sections that rise and fall, and require many walljumps. 

this might all sound like a "i need to get good" comment, but i just thought it'd point it out anyway, since i don't think i ever got this feeling with regards to the classic sonic levels.

good stuff. keep it up

Cute game is cute!

Also I'm not sure if this is a bug but spamming the burst button could lead to losing the wheel and just get stuck on the floor. It takes a few burst uses and momentum to "re enabled" the wheel. Perhaps I'm just using the mechanic wrong.

An actually good platformer? No way.

It's very fun and intuitive. I really like how the time slows down when you charge the sling. I had no problem except that the camera got stuck in the last level and it wouldn't let me advance, so I had to kill myself. Probably it's because of the turret. In the same level you can go on the roof of the structures and skip half the level. Finished in 7 minutes.

The character is also very cute. Keep it up!

I played in firefox browser with no issues.

3rd level with collecting CDs took me nearly 8 minutes (I had trouble getting to the higher part of the level) At first I also thought that level was just a loop and I was supposed to make 3 laps, and not collect 3 CDs.

I died in 4th level on spikes. I could not figure out how to build enough momentum on the big U shaped room.

I am sure the game is going to be big with sonic robot furry fandom.

I found it odd how the player cannot change the direction mid air, but maybe it would make the burst too good. I am not sure if it was your design decision, or just something you overlooked.

This is great, I loved it. Love the classic sega sound chip, love the retro sonic movement, although it is not exactly the same I think, love the momentum based jumping, loved the cute character design. I bought your previous game, pretty recently, think I am gonna buy this one too when the time comes. 

One request as you develop this:  this is just a demo but make sure the levels in the end are visually distinct from each other, environmental visuals was always a part of the charm of sonic 1 -3 , Knuckles and CD. 

And one comment: I don't get the burst, I may have completely misunderstood how to use it.

Fun! I also love the design of the main character, very cute. That one level that loops infinitely fucked me up because i'm used to the top path being the best in these types of games. The game is at it's best when you get into a flow and are flying through the levels at top speed. Good job!
