Transformice!

[Joe's Crab Shack]

It's a French flash game about mice trying to get cheese first. It's a simple concept, but there can be (and usually is) upwards of 25 players in a single room trying to get through a series of puzzles and hazards on a map to get the cheese. Couple this with the fact that on most maps you have a shaman which can build things to aid the mice, or grief them terribly. Then you can also get titles for gaining certain amounts of cheese, getting cheese first, and saving mice as a shaman. As well as customize your mouse with some hats, glasses, etc.

I was wary since it's a French game, but it's very fun and very addictive, plus it's one of the few games i can play at my house with my satellite internet. So i reccomend you at least check it out. Being a regular mouse is pretty straightforward, but shamans often have much more difficult missions and take time to get the gist of. Theres 1 French server, 2 English servers, and 1 Russian server, (though several English rooms have a lot of Portugese and Brazilian players, it's mostly English speakers).
