there's a fine line between fanservice and fun
You're dangling on the fanservice side. The game defenitley works well and has a really solid engine backing it up, but in the end it's really just an overly simplified hack-and-slash with bunnykill characters in it. There's not much fun to be has here past the first 30 seconds. I'm fighting the same enemies in the same environment with the same weapon(they switch in appearence, but not in gameplay). This has potential, but it's just not very fun.
