I like the minimalist design. The climbing mechanic is innovative! It took me abit to get the hang of it. But after that it felt really smooth. Innovative controls are always challenging! Got the same with my game, at the start you need to figure out how stuff works, but the moment you get the hang of it, it feels very satisfying! A timer would have been nice! That way you can challenge people to get to the top faster! It also creates a little bit replayability.
