Left and Right arrow keys, and space to fire yur lazerz. Blast away at the Tie Fighters and dodge Darth Vader and the debris Press V to activate the (useless) targeting computer. Oh and by the way- you can also press the little star or heart to make a sequel of destroying the battle station of your choice come. that's definitely part of the game. By default, music is off, but press m to toggle it. Also press flag twice. Sometimes you explode for no reason if you don't. CURRENTLY INFINITE. No finish. Yet.
STAR WARS!!!!!! K, I know 7 is out. I've seen it. But in all honesty, blowing up Starkiller Base wasn't nearly as cool as the original. At least in my opinion. So you're stuck with blowing up Death Star I for another... three years? All my projects from now on will not be whimsical half finished animations about someone you've never heard of, but more stuff like this. High quality (lolz) games. I actually deleted all of the projects I deemed "unworthy". They're dead now.
