Great game ! I love the fact that each character plays in the same world but it still feels like a new level 'cause you fo to new places.
I think finding the final dude might be too easy to feel like an ending. It took me 30 sec while the other took me 2 minutes so.. yea.
It's super cool that you made it so that if you jump a bit before you hit the floor you'll just jump again as soon as you hit the floor. really pertinent for that kind of game.
Level design is a bit confusing sometime but I guess that's okay
Great work ! :)
