This game is pretty funny. I like the idea and the character designs were cool. Impressive that a whole item shop was made for this game as well.
A small thing that I'd nitpick is the music can be a little repetitive for a game with a long playtime (assuming you have middle-to-bad luck lmao). Maybe more music variety or an option to toggle would be good.
An idea for expansion would be a multiplayer component. I mean, that's a large idea for implementation, but it would be funny to imagine the rounds with friends as you all have different items affecting the "rollette".
