Oh man, count me in for day one with this game. This looks exactly like the kind of game I love. Can't wait to see more!
Man, I'd rather have Towerfall. This looks a lot like Super Meat Boy/1001 Spikes which is not something I'm personally that fond of.
Wouldn't Towerfall be the better fit first? I mean, it's basically made for LOCAL MULTIPLAYER.
Well either way, Celeste looks damn fine.
