If you don't want to install unity web player, grab the windows version of the demo!
In brown, the player controls one or more `browns', whose mission is to reach certain spots in the stage.
The catch is that they can't move independently. The player must use the environment to manipulate both the absolute and relative positions of their browns.
This is a free, playable demo of brown consisting of the first 20 levels of the game (4 worlds). The full version will be available for purchase very soon here, starting with 50 levels and with more being added in updates over time.
