This is one hard son of a gun
I like that every level has a different gimmick that changes your scale, probably one of the best of those "you change sizes" games because of that fact alone. It is REALLY difficult though, i feel like if half those spikes that were placed were not there the game would be alot fun to play, since to make it in time for some of those jumps you have to be really precise. Also the walls are a little sticky, which is especially noticable on level 7
Very fun though! I really like how its executed
