Olu is a rail shooter game inspired by Q Entertainment's Rez, where players use a reticule to target enemies and destroy them for points. At the end of each area is a red cube that you must shoot in order to progress to the next section.

Both the Xbox 360 controller and keyboard controls are supported, although you will need the latest version of DirectX 9.0c, .NET Framework 2.0 and XNA Framework 2.0 to get the game working on your PC.
