I'm curious as to what kind of 2D games the touch arcade community feels are absent from mobile, or just game types there needs to be more of! Name the genre, theme, gameplay elements or even just a title you wish had inspired mobile releases. Personally I'd like to see some Lode Runner: The Legend Returns clones hit the AppStore in inventive ways. I feel like it's puzzle-platformer, single screen levels would work great on mobile devices. How about you?
