Fun game! The visuals were simple but could have been a little bit cleaner (for example some of the red was different shades). I'd also recommend reducing the amount of different colors. For example, black is clearly a platform and red is clearly death but one room in particular I walked in and now there's a lot more stuff introduced at once (even though the mechanics are mostly the same) which was kind of overwhelming. Speedrunning was fun and the controls felt nice. I'd recommend using a color palette (like from lospec) just to give it a bit more cohesiveness visually, and it's a very small change that can be very impactful. The UI was also just at random points in my screen which was a little bit odd. Hope you make it to the next round as I'm really excited to see where this goes!
*Of course I'm kind of picking at the art but that's just because it feels so close to being really clean and polished and I have a hunch the next round will be visual (;
