13AM Games' upcoming Wii U eShop game Runbow is a ridiculous nine-player multiplayer game. Yes, that's right: nine players. It's a party platforming game where the background color dictates what platforms are usable. The colors can be changed on the GamePad by a player referred to as the ColorMaster.

Runbow features seven different modes, including a 30-minute hardcore platforming challenge called the Bowhemoth. It also has a really bouncy energy to it, thanks to the vibrant art style and upbeat, fast-paced music.

Check out the trailer below for the latest footage of Runbow, which is due out later this year. The game will be at GDC and PAX East, so if you're coming to PAX East, find the NWR folk there and we can try playing this crazy game together.
