This game is my litmus test for determining who likes objectively bad entertainment. The game isn't accessible. The juxtaposition of mechanics and interactability is parasitic. Bosses feel more like clunky timesinks than legitimate challenges that spur player growth. You should never spend more time in menus than on gameplay.
Playing this game as a follow-up to a button-mashing platformer birthed from cartoons for literal children feels like being given a Philosophy test for a middle school math final— thematically incongruent, sadistic and unforgiving. If you want a challenging game that understands difficulty, try Dark Souls. This game doesn't know what it wants to be, and fails to cohesively pair card games and RPG elements into a product that's at least fun, if not something that makes sense.
