Trying out different party compositions and builds and the like is very fun and probably the core selling point of the game. Sets itself apart from other card-based roguelites by 1. giving you 4 characters, and 2. giving you massive control over what winds up in their decks (in adventure mode, anyway), so you can deckbuild super freely. To that end, there's a lot to experiment with and a lot of fun to be had if you like the genre, but the core design and balance is just not on the level of slay the spire or others. Also, the last world takes way too long to get through and turns the end of most runs into a chore, especially if you have a good run going and winning is practically a foregone conclusion.
