Aperture Science 2-Dimentional Testing Initiative.

Controls are listed in "OPTIONS" on the title screen.

One of Aperture Science's tests, before GladOS took over, the Aperture Science 2-Dimentional Testing Initiative.

Known issues:

Emancipation grills are easy to avoid.

Changing video settings rapidly cause the game to freeze and crash.

Held objects do not have collision, leading to possible soft locks until you start a new game.

Cameras sometimes do not get effected by gravity when knocked down.

All values may default to 0, such as volumes or mouse sensitivty, to fix, change them or press the Reset button in settings.

Buttons may sometimes break, softlocking the game unset you restart.

If you find any other issues, please comment them. (It is unlikely I will update this game, but alas)
