Okay, first the elephant in the room: It's a bit boring gameplay-wise having it entirely be RNG. It can work, but you instead need to focus on the emotional experience the same way a movie would.
I won... but didn't feel like I did anything to deserve a "win" and there was nothing that made me care if my character lost fingers. That's not a good sign for this type of game.
The sound design was nice.
The music was good at first but became repetitive and annoying very quickly. I can't stress enough how big of an issue this was. Having to keep listening to it for so long was more of a punishment than losing my fingers.
The voice acting and art was okay.
It was a nice attempt, and I think you'll have something cool if you keep working on this. Right now though, I'm afraid it's hard to say much positive about this game. I just don't feel connected to the gameplay, nor invested in the character's fate.
There's just nothing that really makes me care in this game's current condition. However, I don't think this game is irredeemable. Keep working on it! Figure out a way to make us invested in wanting to win. Make us feel powerless, make us want to beg for the dice to save us from losing our fingers. I want to feel the sensation of rolling the dice as if it's me doing it, not just pressing a button. Make the event of having the finger cut off feel very unpleasant to the player to make sure they don't want to see it happen. Make us feel like we're the one putting our hand out for the knife's punishment. Stir up some big powerful emotions. Then you'll have an incredible interactive experience here. Good luck!
