This game is incredibly fun and can be treated like a puzzle game which has multiple solutions per level. The simple mechanics of the game are fun enough that when I beat the demo I went back in just to see what I could get on top of and jump down onto. The only limits in the game are ones that serve to make the game more fun.
One thing I would like to see from this game is more encouragement to start jumping while climbing. I think horizontal movement while climbing should be further limited so you have to make more leaps where you have to jump to move horizontally then latch onto the wall again, but the current system is still just fine how it is.
