Learn to control a rough rocket floating in an sketched fluid and friction free world. Don't expect it to drive like a car or fly like a plane. It'll drift any way it's pushed.
The early levels may be easy for some, providing the chance to test out the game's physics. Later levels involve tackling one enemy after another, all the while negotiating tight spaces in moving scenery.
The horizontal lines on the page may strobe at some zoom scales but they'll help you avoid motion sickness on the later levels!
