Really cool and creative idea to make a game revolving around colors like that! The controls may feel a bit clunky at the moment, but I would love to see a full game develop out of this! :D

If you'd like a suggestion, I'd recommend firstly making the color selection more immediate -- the gun selecting the colors is a really cool aesthetic, but I'd make it select them either with fully dedicated keys, or complete mouse control (e.g. with a color wheel)

Secondly, having a bit of spare health like 3 hearts/hits before dying would be great! It's very easy to accidentally slip and fall onto a blob on the ground that you couldn't see and have to re-do the level from scratch haha

I really wish you could jump with W (or up). Pressing the space bar feels a bit awkward because you also have to use the mouse. But maybe that's just a personal preference.

It took me quite a while to get past the snake. The platform mechanics could be worked on a bit more. At the beginning I didn't notice that I was generating them at the bottom of the screen. But maybe that's just because of the limited time and the looming deadline.

The idea that you can manipulate the world by recolouring it is great. And I like the design, it's cute. Good luck with future development. You are on your way to an interesting game. :)

Well done, you a have made a very Interesting game, I like the ink gun mechanic a lot. Nice graphics and the music fits well and isn't annoying.  Looking forward to seeing you develop this further.

Really cool idea for a mechanic! I had a hard time understanding how to advance past the opening though, because there wasn't any way to get past the first snake enemy. Eventualy I realized that it seems like you can spawn a platform using the paintbrush, stand on top, and get yourself to the end of every level just by doing that.

I'd love to see the paint gun mechanic utilized more from the beginning of the game, because you have a really cool mechanic built but the game never seems to make me make use of it. 

I actually recorded my playthrough. If you want to see my impressions as I played, you can see it below (timestamp for your game in the description). Hope that can be useful!
