Funny idea! Love the mechanics, but it was a bit too difficult to navigate, and could not go bast the first level. Having the 3 balls with these mechanics are awesome, the problem with them is, all move you, but in order to reuse them you need to come back to them. So it becomes more like a puzzle than a platformer.
Maybe go either the platformer route or the puzzler.
Platformer: => Hard jumps to land.
Puzzler: => Way smaller maps, slow time during jumps to make it easier and focus on the puzzling aspect :)
If you have some time to check out our game, it would be also very nice to hear your feedback :)
