It's a platformer where the objective is to get the cheese. About 30 people or so would be in a room and it would randomly select one of those players to be a Magic Mouse and the rest of the players to be regular Mice. Regular Mice could only run and jump but the Magic Mouse could make platforms which were required to get the cheese unless it was a custom map that sucked. Technically both sides could work together but that never really happened. In general the regular Mice would try to get the cheese at the first possible moment the Magic Mouse allowed and the Magic Mouse would attempt to kill as many regular Mice as possible through trickery and then also get the cheese.
It was a fun sort of power dynamic that was infinitely replayable and as long as you weren't super investing in winning it was fun.
