Use LEFT/RIGHT to rotate. UP/SPACE fires engines. Use the '2' key to speed up the simulation, and the '1' key to slow it down. Click on the options in the heading autopilot to hold a heading. 'Vel+' points you in the direction you're traveling. 'Vel-' points you in the opposite direction. 'Kill Rot' tries to lock to the current heading and stop your rotation.
--Changes in this version-- -Usable heading autopilot! Go PID controllers! -Better orbit simulation! -Added time warp that doesn't tear things apart!
