Music's not bad. Game's short but goofy and fun, and the art's nice (Got a dynamic feel to battle sprites which I appreciate.) . The mechanics have potential though they're a bit basic.
Overall, I think you should follow up on this (Also it seems like the game was meant to end after Mokou for this demo, but it doesn't make that very clear at all. I can't continue beyond that point so if there's more just tell me)
