There are several Apps bearing the generic name Demon Hunter, but the one we want bears the full name Demon Hunter – Full Version (iOS). Just in case you give some sort of crap.
Anyway, Demon Hunter is a Japanese sidescrolling action-RPG, with emphasis on the Japanese. It boasts an anime art style and a charmingly sub-par English localization. Plus, there are buttons and menus everywhere. It’s actually pretty solid once you get into it, so it’s worth a download.
Can’t say fairer than that!
