Really fun! at first I was intimidated by the 100 gold requirement, but after a few tries I got the gist of it and it felt really satisfying to beat, I beat it twice in fact!
Really appreciated the ghostball mechanic, it was a simple yet clever way of showing the trajectory. I also loved the deal with the devil mechanic, it mixes strategy with skill very well! And the ominous "or your soul is MINE" text really gave it some weight!
Good game!
