2d side scroller platformer (not sure if pixel or not, might be), two characters a guy and girl, you play as girl and i think at the end there's a plot twist that the guy is evil (you might be the guy and girl is evil not sure)
They're not side-scrollers, but maybe it's The Company of Myself (told from the guy's point of view), its sequel Fixation (from the girl's saner point of view), or maybe I saw her standing there (In which the girl is a zombie and tries to eat you). Please give more details if you want help.
