This game was super cool! Racing against yourself backwards is a super unique idea that 100% fits the theme. I think my main complaints are the slow speed of the character and the level difficulty. Almost every level except the last one is only solved by "red stuff first, green stuff second", so if you do continue working on this in the future it would be cool to see more puzzle-y/reaction-y levels like that last one. But I understand it was only a week, and honestly I am super impressed with the level of polish you got in that short of a time! Great job!
