A mix of buckshot roulette and clover pit, maybe a little to derivative of the first one (especially in the starting cutscene, but it's iconi so I understand why you wanted to do it that way)
At a certain point the opponent told be to cut my ear twice and then nothing more, the game froze and I couldn't do anything else. Aside for this bug that could happen I suggest to make the dice really roll (and maybe explain how the score is calculated)
Anyway really outstanding work for a game jam, it feels like a finished game!
If you try mine, let me know what you think!
