There is a JACKPOT ennemy that appeared in a seemingly random time. He followed me in all levels and it's unkillable and it ruined the entire fun of the game.
if the jackpot didn't go away ever it is a bug I hadn't discovered. The Jackpot enemy is triggered by rolling, every time you roll you have a chance to "win the jackpot" which is bad.
were you able to play after refreshing the browser? I haven't heard of anyone else experiencing this bug so I don't think it's common. I'll take a look at the code for a post jam update.
