Slay the Spire

Great Ideas on all aspects. Good loop. Fun art/lore. Does require loads of time to get the most of build a good deck/rng. Too much rng per run on cards recieved [large pool of cards] or shop location to clean up the deck. Otherwise Great game.

Long story short, a brilliant easy-to-learn game that is very satisfying to win. But you don't win that much. :)

Disclaimer: I own this twice on other platforms not GOG. Simple to learn, play, and find success in runs but challenging to fully learn and master. As you master skills of deckbuilding and choices, the Ascension system will help push your limit and learn further. Every time you beat the game, you unlock the choice to start a run on the next Ascension level. You can always choose to go back and play the normal game or any lower level Ascensions so if you don't find the system fun or are struggling and just want to relax, you can just crank the difficulty back down. While there are obvious relic & card combinations that encourage synergy, the most successful way to play is to be adaptive to the holes in your gameplan and patch those up as best as possible. So forcing an archetypal deck can be detrimental once you start cranking up the Ascension numbers.

Buy it!

I searched for a perfect game to play on the treadmill for a long time, and this is it. Turn-based, so no reflexes required. Tap and swipe coarse movements, so no precision required. And it keeps my mind occupied extremely well. Challenging and compelling. I'm up to 400 hours, and have lost tons of weight.
