Okay guys, new version uploaded. You can now use spacebar to shoot, the levels are shorter, some small bugs have been fixed and you'll find some interesting bits the further you get into the game :)
Also i've noticed the ratings on this game creeping up each day, lets keep it that way.
I'm aiming for 3 / 5
Enjoy!
I've added shooting on my local version, adjusted spawns of missile. Made levels shorter. Half way through adding powerups although its proving complex :/
