Super cool game! Really creative use of the genre too.
I did find a weird bug where the ball just permanently deflated, and didn't stop the run. But it also persisted into the next run. Fortunately this was after I already beat the game.
This also happened to me at some point and I was sure somebody would encounter it and (justifiably) tank my rating, I’m going to hopefully do an update today to fix and polish some remaining issues :)
