Use WASD to move the ship, arrow keys to move the target, space to fire phasers, E to fire photons, and Q to initiate tachyon beam. Watch out for Klingon birds of prey! They have cloaks. Use tachyon beam to locate cloaked ships. Watch your power level! If you don't have enough, then you can't use tachyon beam, phasers, or photons.
I did not create most of the sounds or art.
