To start things off, in the first level, to move player one you need to press W to go up and S to go down. To control player 2 you need to use the up and down arrows. To shoot, for player 1, press Q. To shoot for player 2, press the space bar. The second level contains a noob. To control it you need to use the arrows and try to move it to the portal without touching any of the UFOS.
I made this projects using variables, broadcasts and many other blocks. Enjoy the game. :)
