I got this game for the same reason as Ryza; a joke. And just like that game, I actually had a blast with this one as well. This is my first non-Pokemon mystery dungeon game, and I feel it was pretty simple to learn. As time goes on, I suffered large defeats that caused me to rage quit the game, but I kept getting drawn back in to eventually complete the game as well as some endgame stuff. There are three longer dungeons that I decided to not do (for now, at least), since I feel I've gotten the maximum amount of enjoyment from this game.

Also, this game is unabashedly adult in sexual content. If anything about that puts you off, then I suggest avoiding it. No nudity or anything, but if you're unsure if you'd be okay with this game's adult content, I suggest reading and watching the trailers on the game's store page to make a decision. But overall, I really enjoyed my time with this game.
