While it's impressive that this was made in 2 hours, the game is difficult to play and feels overall unpolished, also the theme relating to the chains feels like a stretch.

I tried hard to find a good game idea, unfortunately, I was already late for the jam that I didn't have time for anything I could think of. The best I could think of was a Flappy Birdlike game with some chains.
I am planning of polishing it up a bit after the jam. You can come back and play any time to see the changes.
Thanks!
