This is an extremely rough draft of a multiplication math game I'm building. The object is to "eject" all of the aliens to space. To do that, you place rockets near them or under them, timed to go off when they are touching them, and set with the proper combination of factors. The games requires a keyboard and mouse. To change the factors, click either of the factor boxes, and select a new set of factors. To place a rocket, click on the player sprite. Use the arrow keys to move and jump.
