Hooray! Hades is out of the Epic exclusivity rubbish and available to everyone now. You play as Prince Zagreus (Hades' son) and you've decided to leave the underworld. This manifests itself as a roguelike with incremental upgrades using currency from each failed escape attempt. Each room you enter is different every time, and filled with increasingly difficult enemies. The gameplay is hard and heavily focuses on dodging and awareness. Animations are top-notch and the gameplay is really fluid.
I beat the final boss after 18 runs. One thing I wasn't sure how they'd handle was a reason to keep playing after beating it, but they've actually woven a perfectly plausible story reason into the game to make both the roguelike nature make sense, and give you a reason to keep playing after finishing it.
