I have finally found the right comparison : it is a "Slay the Spire" like with different and unique mechanisms. Just maybe harder.

Meh. It has a lot of problems, text is rather gibberish and the gameplay pretty dull & very limited. Played 3 runs and I keep seeing the same 4 or 5 enemies. Too few utilities loot (heal & torches) and the save is non existent: you actually save a rings collection, if you manage to get to the collection save without dying that is. Annnd every run you can only add 2 rings to your collection. Not many rings to find either. Some stuff is OP while the rest sucks terribly. The tutorial is almost useless and there's a lot of shady stuff lol. Sure it's an EA, but there's a lot of stuff to do to straighten that up. Concept is amazing though. TLDR: Meh.

It's good and something unique. The only thing I dislike in this game is the way it saves your progress. I hope they change that in the future.

It is a solo game. A kind of dungeon crawler with improving character. Game mechanism is really interesting, close to deck games but different. A nice discovery for me. Try it !
