Transformice

Transformice is a hilarious, ever-changing platformer that puts you and a bunch of your fellow mice in a race to capture the most cheese and become the all-powerful mouse shaman. The shaman has amazing powers, which can help or hinder her and her fellow mice. However it goes, it's sure to be a riotous good time!

Players compete on any of a number of maps, whether made by the developers or the community. Shamans can place objects on the map to help people get to hard-to-reach spots -- or block off the competition. Shamans can progress their powers through skill trees, providing RPG-like customization to complement the zany and unpredictable action!
