What is Primary all about

Primary is about Roy, a super soldier in the land of the HUEman (get it? Ya we are lame.), who must climb to the top of Prizim tower to try to find a way to close the portal that is allowing horrible black goopy creatures into his world.

NOTE: You can play with an x-box controller with an emulator like Xpadder, I am told this also fixes the "Sticky Keys" bug. The elevator menu is able to be controlled with the keyboard as soon as the game has saved so you don't have to use the mouse if you don't want to.
The idea behind this wonderful platformer is that you can take on any of the three primary colours of light (red, blue, yellow), and each of these has its own unique talents:

Blue can make ice cubes. These can be used to hold down buttons, and you can jump on them to reach a little higher when you jump. At the start of the game they vanish when you change colour or drop a new cube, but on level 18 you gain an upgrade that lets them stick around when you change colours. They also melt over time, so when they're holding down a button you may need to be a little quick. Drop a cube by pressing the spacebar.

Red can shoot fire, which kills enemies. Enemies drop orbs, which give you points if you collect them. Shoot fire by pressing the spacebar. On level 26 you gain the Fire Boost (flame/super jump), which lets you jump higher when you're red by holding the shift key. If you're using Windows, make sure you turn off sticky keys before playing, or you may have problems.

Yellow can turn intangible and invisible by pressing S. While intangible you cannot be hurt, but you also can't do anything until you return to normal. You need to move around via moving floors and sliding on slipper platforms when in this state. At level 11 you gain teleport portals, which allow you to drop two portals using the spacebar, and then use R to teleport between them. The third portal you drop will replace the first, the fourth will replace the second, etc. Checkpoints are also gained while yellow.
