You might've heard about Nuzlocke challenge in Pokemon fandom, once it faints, your monster is impossible to be used again. I found that this unique challenge could work in Rayman Origins, with its small roster of playable skins. I've made this website to be a "progress tracker" in the challenge, for fun. :3
Sorry I'm not a good graphic designer :/
The rules:
Losing a life makes the currently worn skin impossible to be used again. You have to restart the stage and start from scratch.
