Kid Icarus game. The styles vary from fantasy cover art to Bruce Timm-style minimalism, but they all have one thing in common: Pit is a troubled young man. This fits with the proposed game pitch, in which Pit is "cursed for thousands of years and becomes a fallen angel." He bears a tattoo on his arm that details his crime. Awesome.
We hope this is fake, or not what Factor 5 (or whoever the real developer is) goes with. It's not even a matter of nostalgia: we need more weird flying platformers about eggplant wizards and fewer games about brooding antiheroes. We don't need Man Icarus.
