I got the gist of the game pretty quick, which is really cool! Can definitely see the Balatro vibes, especially on visuals and music.
I had fun with the rounds even with this level of simplicity, which says a lot. Adding more elements and relying on addictive gameplay, point / score maxing and you probably have a very solid game in your hands.
Not too much I can add that hasn't been said, lacking a tutorial makes things a bit hard, and once you figure out the game it gets repetitive fast. Having power ups, items and increased chaos would be a perfect way to add to it.
Very impressive for 43h!
Nice submission.
