Ive been loving this game. Its a card game with lots of depth to the optimization and some RNG but its not overly punishing. If youre looking for a fun casual game try it out! Its less than $10 on sale right now.
Once you're finished up with it, I really recommend Monster Train. Slay the Spire is great, but I never finished it 100%. Monster Train I still go back to randomly even after putting 100+ hours into it. The game actively encourages you to try and break it, finding the right combination of cards and artifacts to truly be OP. I think it would even be impossible to beat most of the difficulties if you don't lean into that.
It's funny, I feel the same way just reversed. Really liked both, but StS is a forever game for me and I think it's the game I own on the most platforms (PC, switch, and android)
