The problem has been found, and a patch will be uploaded shortly after voting is over! Thanks for playing our game, and you really missed nothing. You are correct that the bug was caused by the genie's difficulty resetting, however the bug only occurs once you had already beaten the genie, and after that there was supposed to be a win screen, but the glitch happened instead. You didn't miss any gameplay, so I hope you can judge the game based on what you experienced up to that point. Hope you enjoyed!
