Transformice

In this game you are a mouse and your objective, obviously, is to take the cheese and take it to the burrow.

Avoid obstacles, rivals, map traps and other difficulties to reach your goal. Compete against other mice for cheeses, titles, medals and level up; you can also specialize as a shaman and earn points by helping mice reach the cheese.

To make the experience more enjoyable, you can also customize your mouse: from the hair (yes, here mice have hair) to their coats.

Transformice is available in its web version and downloadable for windows, in addition to its Steam version.
