The only game in which you can play as a mouse trying to get cheese....while having a shaman help (read:troll) you. Involves things like rotating planks, portals, bouncy wood, cannonballs, and the all-important Anvil God.
example of a transformice game:
trollmouse: LOL, cannon them shaman
trolledplayerone, trolledplayertwo, trolledplayerthree: FFFFFF
luckymouse: LOL, missed.
