This game is an absolute gem! The player switching mechanic is fantastic and allows for some really interesting levels that would normally only be possible in co-op.
My only complaint is that the focus on wall jump makes the game a lot more difficult. I found myself having to repeat levels or wasting player cycles because I was messing up my wall jump. I think levels that require no wall jump or maybe a double jump would have been much more manageable.
Fantastic work!
