i am so sorry! i just realized the error and i think i fixed it, you can delete the old version and download it again, see if it works! if not you can tell me again what bug is happening!
But that's exactly what I did when I detected the problem.
After the correction I found another problem: the difficulty of the levels in world 2 is a bit too high, especially level 3, which seems impossible due to the way the area is designed where there are two red spiked balls orbiting very quickly.
