The terminators are coming! Keep them away - don't let them cross the red line - for 60 seconds! Using a big magnet! W/S keys to move camera forwards / backwards. ARROW keys to move magnet. SPACEBAR to activate magnet (release to drop).
This is a silly game, mainly done to use the stickman points roughly copied from a cool motion-capture demo at http://www.biomotionlab.ca/Demos/BMLwalker.html.
