The idea is really good, and the game deserves to be developped further more.

It would be nice to have quality of life improvement.
For instance, start with a given low pair hand. It feels bad to be game-over without playing because I chose the chip instead of the cards at the first shop.

The blur on the border of the screen adds a nice touch, but when you have lots of cards, it becomes hard to read.
Also when you have a lot of cards in hand, it's hard to find what you want.

I would also love to know my stats (hp regen, health up, ...)

Maybe showing the target of a card on hover would be nice too.

I'm looking forward to future updates !
