Rainbow Frontier

Somebody drained the colour out of the frontier and left it grey. Nobody knows who. Nobody is going to fix it either, except you and your unicorn.

So you ride. You gallop face first through Grey Growths until they give up, you wake the Grey Beast that thinks it owns the place and headbutt it until it stops, then you switch the Rainbow Beacon back on like a very dramatic light switch. Do that three times and the wild is restored. Congratulations, you saved everything.

It is online, so the other unicorns wandering past are real people and not decoration. World progress is shared, which means if some stranger already cleaned up a region before you got there, great, that is less work for you. Bump into someone and you can play Hoof and Cross, which is tic-tac-toe you play by physically standing on a giant stone board, because obviously.

The whole thing, the world, the unicorns, the music and the multiplayer, is 13 kilobytes. Your last selfie is bigger.
