]] of mice trying to get as many pieces of cheese back to the hole as possible on various deathtrap-laden maps. Among the mice is a Shaman, who can conjure up a variety of items to help his disciples in their task. Sometimes, the game will add a bit of competition by selecting two Shamans and pitting them against each other in a fight over who can get more mice to the hole of their color.Because getting in each other's way is of course what this game is all about. Most maps are completely trivial and could easily be navigated successfully with zero casualties if it weren't for the fact that the mice tend to rush recklessly forward at the earliest opportunity. There are two reasons for this. The first reason lies in the scoring system. The player with the highest score gets to be Shaman in the next round, then their score is reset and they start over. Players score points by bringing cheese to the hole, and the more people they are quicker than, the more points they get. The second reason is that getting cheese first unlocks various titles. The consequences of this arrangement are apparent.Seeing as this is a browser game that anyone can play at any time, it offers a unique insight into the Internet's collective consciousness. The game currently runs on the following servers:
Chained Heat: Several levels revolve around pairing off mice and tethering them to each other, forcing them to work together to survive and sometimes to reach otherwise unreachable cheese. Some of them succeed.
Cosmetic Award: Fulfilling certain criteria unlocks various titles, such as "Pirate Mouse", "Mouse On Strike", "Accomplished Shaman" or "Nice Mouse". Players can use any title they've already unlocked. You can also buy various accessories such as hats with cheese in the shop.
Critical Encumbrance Failure: Caused by chocolate ground. Without cheese, you can run across a bit slower than normal. With cheese, you aren't going anywhere.
Dronejam: Some levels cause the mice to physically interact, pushing each other around. These maps are inevitably built around bottomless pits and/or long narrow passages that need to be traversed both ways and through which mice can only pass single-file.
Cranium Ride often results as a convenient way to traverse said pits, much to the frustration of the mice being ridden.
Dummied Out: There was a version with portals (later said to be a 'test of a piece of code'), which were removed after a massive fanoutcry. Later versions re-included them in a specific couple of levels.
There also was a super-spirit at one point, but it was removed after a few days for being massively overpowered.
Eldritch Abomination: Through dark shaman troll magic and abuse of Transformice physics, shamans are able to create a flying aberration formed of anvil tentacles; the aforementioned Anvil God. In one of the maps, you must face a resident Anvil God to get the cheese.
Escort Mission: The entire premise of the game. Interestingly, all the escortees are controlled by other players, proving that real intelligence performs no better in these than artificial one.
Explosion Propulsion: It is possible to use bomb explosions to propel the mouse to the exit faster than would be possible by running, but pulling this off on purpose is tricky.
There's also Spirit, an invokable-by-shaman explosion. There is at least one level built around it.
Two levels are built around the shaman creating balls that explode after a few seconds, rather than the usual kind.
Frictionless Ice: Annoyingly, ice walls can't be walljumped off of, which is especially deadly when jumping from one thin ice spike to another.
Game-Breaking Bug: The game's physics engine can, on occasion, sabotage a Shaman's bridge-building efforts simply because of the odd ways in which the various pieces interact with each other. Fortunately, because it only affects one stage at a time, it can be very entertaining to watch.
When two shamans each build an item at the same time, the game can occasionally get their properties mixed up, resulting in the items being physically connected to each other despite being in two different parts of the room. Then they start interacting with the environment."LOL PHYSICS" indeed.
The same thing used to happen with snowballs.
Gimmick Level: There's the occasional upside-down level. This includes the mice's names and speech bubbles.
Good Bad Bugs: The walljump and airjump. A good portion of the user made levels require people to use these in order to win.
Gravity Screw: There's a level in which the gravity switches after a few seconds. Naturally, it consists of a flat floor, has no roof or platforms of any kind, and the sky kills you.
Griefing: If a Shaman is a dick, there is not much the other mice can do about it. It is also possible on certain maps to screw over other players.
Imagine if the other players had a deliberate means of knocking other players and shamans off precarious platforms and messing up careful structural design, including pushing invisible objects. Well, thanks to the likely seasonal addition of snowballs, they did, but they have been removed.
Luck-Based Mission: Your success in most of the pusher maps depends entirely on where you spawn in the mouse pile. Most levels are also impossible to finish if you happen to get a shaman who doesn't know what to do.
Also, the Fan God maps. The shaman is supposed to stop the fan from moving, but if the shaman dies while doing so/doesn't know what to do/is AFK or if you want to be first, you just have to run under it and pray that it won't fling you off the screen.
Map 99, if you want first.
In map 41, you start in a special car that the Shaman is supposed to push to the cheese and back. You better hope you glitch out of the box, or no cheese for you ^_^
Pit Trap: How about a fake floor surrounded by normal, visually indistinguishable floor? Located on a map that looks identical to another map, which has a normal solid floor throughout?
How about a level with four chunks of cheese, three of which have under them aforementioned invisible pits? How about having these pits distributed randomly each time the level starts? Yeah...
Randomly Drops: The Christmas presents in the 2011 Christmas event have a 10% chance of giving you an item, 40% chance of giving you a piece of cheese, and 50% chance of giving you nothing whatsoever.
Spring Jump: The shaman can summon a trampoline on most maps. There's also a map that is essentially an enclosed box with walls that bounce mice up to warp speed.
Then there's lava, which will make you fly off the screen unless you hold the jump button when jumping on it.
