This game would be really fun if you weren't so stingy with the money. I see you had inspiration from Balatro. Notice that when you play Baltro, after each round you have money to make at least one (sometimes several) purchases from the store, leading to actual decisions. With only being able to afford 0 or 1 items from the store, there's a lot less decision-making in your game and rerolling feels really bad.
Also, it's very hard.
