I like the art and sound design, although it took me a game or two to figure out I was supposed to avoid the green ones too. I wish the character moved a bit faster to make it possible to survive a bit longer – right now it kind of sets a maximum possible length to the game (personally I couldn’t make it past 35s) and lowers the skill ceiling.
Overall it’s a fun concept and solid execution, though I do wonder what more one could do with this mechanic or how one might explore this further.
