So, this was a game I played in early 2010s, that was sort of like Transformice. There were two teams: black mice and white mice. The goal of the game was to reach the cheese in the post. I remember also that the teams were running from something, but don't remember what it was. There were hundreds of mice, so I think they were bots The graphics were lineless 2D. You didn't need to register or anything like that. I played this on a website that hosted many other browser games, think of Miniclip or GirlsGoGames, but it was a more obscure site as I remember it.
