It’s a low budget indie game. I would say pretty damn good for 30 bucks brand new. Don’t look up any spoilers and you will get pleasantly surprised by the game changes. Probably about 12-15 hours of original gameplay, but it adds a harder mode after you beat it. The shells are unique but powers aren’t great. The harden ability is quite OP, but good luck not using it. A good variety of enemies and boss battles. Don’t compare it to the souls series! It’s an indie game for 30 bucks not a triple A title that ends up charging 90 for the full game.
