Gameplay.
The aim of the game is to collect the cheese as a mouse and take it back to the mouse hole. Players control the mouse with the arrow keys.
When a player gets the highest score on the scoreboard, they will become a shaman on the next map. The shaman helps other players get the cheese and bring it back to the hole. The shaman can make objects such as planks, boxes, anvils and balloons to create structures.
Cheese can be used to buy clothes for the mouse.
Players can win rewards such as titles, badges and clothes by completing tasks.
Game modes.
"Transformice" has different game modes.
Transformice.
This is the normal mode of "Transformice". It has maps mostly made by players.
Vanilla.
Vanilla is very similar to "Transformice". It only has official maps.
Survivor.

Racing.
In this mode, players compete to finish maps as fast as possible. Shortcuts help finish the map quickly.
Bootcamp.

Defilante.
The map moves horizontally and players must keep up with it. There are points around the map and mice must collect as many as possible before getting the cheese and entering the hole.
Module.
This mode has minigames made by other players using a programming language called Lua. There are over 40 official modules and over 70 semi-official modules.
Village.
There is no objective in this game mode. The map looks like a village, with several non-player characters. Players use the village to chat, roleplay or trade.
Development.
The game was created by Melibellule (real name Mélanie Christin) and Tigrounette (real name Jean-Baptiste Le Marchand). They met at work and became friends. Tigrounette had experience making games in the past and wanted Melibellule to make the artwork. Melibellule came up with the idea of a little mouse who had to get cheese and bring it back to the mouse hole as quickly as possible.
After quitting their jobs, Melibellule and Tigrounette created the gaming company Atelier 801. They later made the games "Run for Cheese!", "Bouboum", "Nekodancer", "Fortoresse", "Dead Maze" and "Tomb Rumble". A sequel called "Transformice Adventures" is being made.
