I’ve managed to hack the game down to 4kb, and it wasn’t easy 
Had to cut off like 3 arms and 5 legs. But it’s playable, hopefully it’s still as fun.

Keys:
W = FORWARD
S = REVERSE
A = STRAFE LEFT
D = STRAFE RIGHT
(Note, all movement is relative to the rotation of the starship!)
Mouse:
Left-Click = Phasers
Special functions:
E = By pressing ‘E’ you travel at warp-speed (you need to press E in combination with W)
Other notes:
Closely monitor the minimap, as you can see where enemies are
Phaser banks recharge with time
Shields and hull recharge with time, but hull slower.
Score count:
Phaser hit = 1 point
Destroying a enemy with phasers = 30 (or total 70)
Description:
After years of war with the Dominion, Starfleet has run out of starships to defend against any invasion. You are the sole starship located near the Neutral Zone, and have detected a huge invasion fleet of Romulan Warbirds making their way to Federation Space. The future of the Federation rests in your hands, defend against the invaders.
Make sure no enemy ships make their way to Federation space, or else all is lost.
Make sure no enemy ships get from top (observe minimap closely) to bottom. Works very similar as Space Invaders, except it’s a lot bigger map and you have to dogfight every enemy vessel.
