Sorry to ask, but why exactly did you submit it to this game jam? It was made a year ago and I don't see any relation with the topic of the jam.

however:

I love the graphic style, very nice! I also like that it has a two player mode. What was irritating was that jumping always cause some lagginess (at least on my computer). I also missed some background music. Also the levels and the whole game could be a bit more elaborate. But aside of that, all in all a nice game.
