It's a dungeon crawler with bonus areas and happy surprise clown present time.
You can fish, weigh your fish in fishing contests, race your fish in the finny frenzy.

And a luscious loli you can buy a revealing cat costume for.
While you have all that you may also evolve your weapons into new and dangerous items and upgrade any stats you personally may want.
