Its a nice, hard game! Sometimes I felt that my jump was a bit random, (sometimes I would jump high, even though it should be the second jump, or things like that), but probably thats also just me beeing bad. Nice game!
Only one thing, the game seemed to be bugged for me in the beginning when it says i should press space. If I press space, I cant move anymore... If i dont, then i can move normally, just a bit strange. ;D
