Try to get as many points as possible by using your laser cannon to stop the aliens from landing while avoiding their lightning bolts. Press any key to start, R to restart, the Space Bar to fire your laser, the Left-Right arrows to move your cannon, and the Up-Down arrows to change the cannon's speed.
Inspired by: https://en.wikipedia.org/wiki/Space_Invaders To male it easier to build on this work, I’ve pulled out a collection of parts and put them in a studio with a bunch of internal comments explaining what all the blocks do. You can find them here: https://scratch.mit.edu/studios/25888810/
