Thanks for the feedback on fall speed. It was meant to be pretty difficult, some of the levels toward the end I struggled to beat as well.
Tough games definitely have an appeal, but my thought process is that you want game jam games to be very accessible so everyone can experience all the work you put into your game. Again that's just my opinion, some people love rage games, but that would be my major piece of feedback. I try to always make things easy to beat so people can see all my design very quickly. The levels in your game were super well executed and I wish I could see them all!!
