The graphics and music are really neat, it's obvious you put a lot of care into them. I love the shading on the fonts! I tried something like that for my game's ending scene and it's a neat effect, especially at this low resolution.

Clever concept, good for a quick little fun. Probably can get a little repetitive after a while, but works well as a jam game. Is there an end goal or is it a pure score chase?

This is a fun little game! The idea is cool and there is a nice amount of detail like the player changing color when picking up a different color! There should be a bit more stuff to do in the game as this is pretty easy and a bit repetitive. For example, you could have randomly generated mazes so you have to navigate your way around a map to collect colors. That would make each game very different and would make you think a bit more about your actions.
