The art style is so cool! The game itself fits the theme really well, too.
One thing I would like to highlight is the font used for the numbers in the game. It's a bit small and hard to read, BUT it's also integrated so well with the art style. Since there are only numbers from 1 to 9, I found "interpreting" them really fun and interesting — it gave the game a lot of personality and an extra layer of fun, in my opinion it was a good decision. The game was very fun, great job!
