This is an interesting twist on the gambling idea! I liked that the enchants were there to mix up the game a bit more than just rolling dice! The Music fits well and I Loved the cutscene at the start! It makes the devil feel very devious and charismatic!
One thing I would say is that the enchants don't "feel" like they're changing anything, and I think this is a situation where you need to rig the randomness so that it feels more fair to the player. For example you could make it impossible for a weighted die to roll a 1 or a 2, as because of the power up the player is told not to expect low numbers from that die anymore, so it feels unfair, even if the chances of rolling higher numbers did increase. Especially if a weighted die rolls low multiple times in a row. It just comes down to human psychology.
But that's just a minor thing, other than that I think this game was quite fun to play! I enjoyed scheming up new strategies every turn to try and roll a higher number, and adding up the dice before I throw to try to make up the difference when I started running out!
