What are the controls?
You didn't tell us the controls. and the graphics are blegh for modern games nowadays. 5 /10 though because of your name.
Where to start.
No preloader, its super easy to beat, and when you beat it nothing happens. Not fit for NG, but nice start.
Incomplete Alien Invaders
No menus, the other... slimes don't shoot back, and nothing happens when you shoot them all down. I wouldn't Blam this, but an update is necessary if you want to keep this game alive in the portal
