Well, it's certainly a very easy game. I don't think there was a single point where I felt threatened by any enemy. And of course, that means the only way to see most sexual content is to lose on purpose, which isn't something I'm going to do. Easy virgin clear, at least. Probably needed some kind of harder difficulty if the dev wanted the players to engage with the sexual content at all.
The cards are interesting, but kind of samey. You quickly get a lot of them, but there's no real reason to change them around too much, so you'll probably ignore most of them. When your basic sword swing interrupts and stunlocks all enemies until they're dead, the cards only real purpose is for the occasional heal and getting a higher DPS on bosses. The Scrooge McDuck attack is a little fun, but too awkward to keep swapping forms to use it, so I generally didn't bother. (I know you can turn off the transformation animation, so maybe I should have done that to experiment more with it).
Map design not too bad, if a little basic; some annoying areas where you have to backtrack to switches if you go the wrong way at first.
