There's a lot of nice themeing across the entire experience with each suit having their own flavor of bad luck.
Once the player gets scaling it felt like I could always stay ahead of the enemy scaling though and only the Hearts blood tax or Clubs enemy speed even had a chance of killing me. The Diamonds attacking me turned into extra XP most of the time in addition to the money as long as I kept my damage up to one-shot them and the boss from the Spades kinda turned into a free boost of XP since I could 2-shot him and not get hit by his charging attack.
Overall a really good execution and a fun game. It felt nicely balanced for a jam entry to let people have more chance of seeing the full experience so if people find it "too easy" then I think it's currently in a good spot, lol.
