green flag to start. left and right arrow keys to move, up arrow to shoot. you have three lives, lose as few as you can from the aliens! the regular aliens give 500 points if you hit them, and the mothership is an extra 7000. the shield can be destroyed by either your shots OR the aliens' shots. good luck!
this is my second-to-last scratch class project. However, I am falling behind a bit. sorry about the lack of add-ons like a shop or exotic alien ships or levels.
