The animations on the roulette are awesome and the music's interesting. The bit of story on the game page sounds interesting as well, it'd be cool to see it worked into the game.
I think there's interesting gameplay here that could be made more interesting with that storyline, but in this state it's tough to get into. There's a lot being thrown at you at once. Which is pretty normal for game jam games of course, it's to test an idea, but it would certainly benefit from an early game section that slowly eases you into all its different mechanics and upgrades.
What wasn't fully clear to me were some of the results. It'll say something like "10 slot chips x 2 multiplier" but then I still just get 10 chips, not 20? But overall, I felt like I was building towards a bit of a strategy with my mushroom colony and I managed to keep hitting the goals that were set.
The text is sometimes unreadable unfortunately. Some text boxes are hidden behind other objects or fall off the screen, some text doesn't fit its own text box. I think you need to make sure your UI/Canvas scales relative to the screen, so everything scales properly on different screen sizes.
