Attack selection memory would be neat, so I don't have to scroll down to the attack I want every time.
I like the weird Madoka text being used for names, health, and all those things related to witches. I can see it being a feature that non-Madoka fans get annoyed at, but your audience is Madoka fans so there's no reason to bother changing it.
You being spotted because the enemies saw your party members is annoying, though i guess makes sense.
Can't move skills without having an extra skill in your menu. I was trying to put my strongest attack as the first default option.
Exp pills feel pretty useless, they don't give enough, and there's a level cap and abundant enemies in each level that almost guarantee that you'll end up at max level by the end anyways.
At maximum corset and max corset skill the corset savant effect would not unlock
Game felt too grindy and repetitive, and I don't really care for the erotic elements, especially Madoka with a dick, so I stopped playing after dungeon 3. with some balancing it could be more fun.
