Amazing! Super polished and fun! The music was a bit repetitive (I could tell that you were using chrome music lab, I prefer BeepBox, but thats just me). The art was really cute and fit the game. A simple fix to make it feel a little bit better is to add a tiny bit of bounciness to the paper which might help them stay off the walls a bit. I also feel like there didn't need to be a button to turn on and off the blower, I kept it on the whole time so it was something I had to do at the beginning of every level. Keep making games your good at it!
Thanks for the feedback and comment!
Also, I actually used Bosca Ceoil for music :)
