GhostHouse is an old tech demo by Oliver Pearl, creator of MinuteMatch and Bonbon Quest among others. Many shades of sepia were used although the game has poor collision and plain textures. This 2MB FPS only features one weapon and presents no configuration menu.

Still, it's amusing to see past projects from the current crop of independent developers long before achieving fame and success.
