Had to come back and play more. I think I found the limit.

I’m planning to drop a big update after the jam, so you should definitely stop by and check it out again when you have some free time xd.
Right now, no one can actually finish a run because of those bounce pads—the balls just keep bouncing forever haha!
I realized I already rated your game but forgot to leave a comment, so I’m going to play it again right now and leave some proper feedback for you.
