The Player, in the starter building.

The starter building is the starting point in Canabalt. Unlike the rest of the world, it is not randomly generated. It appears to be some kind of office building. When the game begins, the building starts to crumble as if it is about to fall. This may be why the player started running in the first place. If the player fails to make it out, the death message: "you ran -m before just barely stumbling out of the first hallway" appears.
