Interesting concept, but I got stuck in a level where I can't make any jumps as the first ball. The spacebar creates a new ball, which I assume is not intended. I think the level designs could be better too to focus on the rewinding players.
haha tank you ! i made all the level design 1 hour after the deadline :// the space bar was just me playing around. You can also press C to enter create mode and places player goal and walls !
