Loop Hero! It’s free on Epic right now and I’ve been really enjoying it! A nice blend of procedural generation, deck building, and roguelike allow it to be a very rewarding and engrossing experience overall where I feel I’m consistently progressing.
I still haven’t been able to beat The Lich yet, but little by little I’m knocking his health down that much further to make the loop (heh) feel rewarding!
I haven’t played it but I heard about it on a podcast I enjoy: Podquisition. One of the hosts - Laura K Buzz - seemed favourable towards it and recommended it to those drawn to that style of quick to understand but continuously engaging games with simple tasks to complete, and after listening it genuinely made me want to give it a shot.
