Stay Inside The Box: The whole game takes place in just one screen, no scrolling or changing screens in any way is allowed.
True Colors: The game uses only the basic 16 colors: black, gray, silver, white, maroon, red, olive, yellow, green, lime, teal, aqua, navy, blue, purple and fuchsia. See color chart
Approved for All Audiences: The game must not show any violence, not even cartoonish. Stepping on living mushrooms is off the list, as is killing any type of enemies, not even undead, though we know they’re already dead…
May the (Web) Force Be with You: The game runs in a browser with no plugin.
