I love Slay the Spire Math Monopoly!
Jokes aside, I actually think this is a pretty cool idea.
(I'm not a huge fan of Math kind of ironic coming from a programmer)
But I think this could be honestly an educational game for a younger audience.
I like the niche powerups you get as well. I've always preferred niche build type of powerups opposed to super generic ones.
The only "bug" i had really was some clipping audio. So to me it seems like you did quite a lot to this game in a relatively short amount of time.
Good job I like it!
