I've made an EXTREMELY innovative RPG idea, so I guess here's my pitch :D
It's a sidescrolling RPG where, like in Chrono Trigger, once you run into an enemy on the field, you enter battle on that particular screen. The catch is, you will have to manipulate the obstacles on that screen that were originally used for platforming to your advantage. The storyline is pretty deep, but it's basically about a girl that lives in a world of light, but then becomes allergic to that light and has to decide if she wants to live in darkness or not.
