Cool looking game. Unfortunately, the game itself lacks some punch. I mostly played without using any mask and went quite far, I think (I didn't finish). As you have many cards to choose from, you can get quite close to 21 and win the round. Some times I used life to get more cards and the life loss is really cheap. So I just started paying for cards and summing up 20 or 21. Became just a game of math...
The visuals and the aesthetic are cool. With some tweaks to the mechanics and rebalancing some resources the game could get quite fun. Maybe some enemies limit the amount of cards you can play per round, others will automatically halve one card on the table. They should do stuff to make you strategize around that.
