The game's solid, but there's some things that could be better about it. Gummi Ship sections feel unnecessary, some bosses (namely Hook and the final phase of the final boss) have frustrating attacks, mashing attack and sometimes healing will get you through 90% of the battles just fine, Monstro is annoying to navigate, having to find all 101 dalmatians, and the AI isn't that great at actually killing things.
It's worth playing just for the novelty of seeing Final Fantasy characters next to Disney characters tbh
