Neat game! I like the cute star character.
I do feel like there were a couple blind jumps here and there which could be a bit annoying at times, and I think having some extra feedback on when an enemy is hit could help a bit, but I do like how the game looks!
I also think the segment where you can choose between being green and red is very cool - makes me feel like I can decide what challenge I want to take on, which feels good!
