Fun little demo. Suppose it would be even more fun if i played with a friend and not alone. As far as i realize there are only 3 simple levels, 2 of which are the tutorial, which is sad because this is quite an interesting concept and I'd like to see what you would come up with. The controls are pretty weird, especially when playing alone (why does player 1 not jump with w if player 2 uses up arrow, also the tutorial said it wrong). Also the third level can be solved in the same way as the second one :). The timer is not that big of a deal because it's quite lenient, but i do think this game would be better of without it (i know it's because of the theme, but I'd hate if i finally made a hard jump and then the timer ended.) All in all, fun concept, needs some work. Keep it up.
