Left and right arrow keys move and space bar to fire. Shoot all the bugs before they get you. It gets harder as you go. You only have 3 lives.
This game is based upon the classic arcade game galaga. It uses cloning a lot and runs very smoothly and fast despite the number of sprites/clones. The number in the middle at the top of the screen is the high score and uses cloud variables, so can you be the best? ---------- If you prefer space invaders try this https://scratch.mit.edu/projects/90937233/
