It's a demo but I really enjoyed playing this. The comparison to Balatro and its popularity has to be made, if only to make it easier to explain the game: it's blackjack instead of poker, and there's a lot of weird cards and funny references.
Some example are a 13 of spades, pi (3.14) of hearts, a PS1 memory card that allows you to copy another card, Yu-Gi-Oh, Pokémon and other trading card cameo appearances, credit cards, business cards, and so on.
The progression is like a classic roguelike deck builder: you move across floors, defeat enemies, make choices between other events like upgrades, healing and adding new cards, defeat a boss and go to the next floor.
I honestly expect this game to get quite popular when / if it releases on Steam. It's already quite polished, has a cool vibe and while blackjack has simple rules, this game adds so many modifiers that it keeps being interesting.
Edit: I'm blind, it released on Steam 3 months ago! Still a great demo haha, ima go and buy this game now
