TLDR: Balatro is a roguelike card game where in you make poker hands to score points. You can enhance cards and get jokers that have more effects.

It wont a ton of awards this past year (it's just about a year old) and was incredibly well received.

Localthunk is the developer. I believe he did everything for the PC version himself (except maybe a single joker's art). He has a publisher that helped port to pretty much every other platform you can think of.
