I'm a few hundred hours in - this game is a masterpiece! I love it, and it's the only game to hold a very big and steadily growing candle to Slay the Spire! I only play Classic Unfair, but I think it's superbly balanced and wonderfully challenging. At first I thought that the "branching factor" (i.e., number of item/hero choices after each level) was too low, but I think it makes for a unique strategic experience that is distinct from Slay the Spire and its clones. Overall, very few mindless decisions, and I am still figuring it out after hundreds of runs. Easy 10/10.
