Menu controls: Arrows to navigate menu and press space to pick option and exit credits. In game: Mouse controlled movement, click to shoot, invaders darken when on half health. 1 to change skin. The number in the bottom right is health. You might need to put your volume up if you can't hear the music. It is quite different to the classic. Credits in game I may have put a secret on the menu screen. If you enjoyed this then maybe follow at @-Oltimate-
