Very good game. Clever mechanics and I love the tutorial explained as you go through the level.
It is a very clever idea.
If I really have to give a suggestion, maybe the feeling of the jump could be a bit improved (Even if I do not know really well to tell you how XD). In any case, this was a very good game, especially given the limited amount of time of the Jab. Good work!
P.S.
Consider trying also my game leaving feedback, I would appreciate it a lot :D
