I only need to tell you that you press s to start the game. DELETE THE CLONES FIRST. That's very important. Or the game will NOT work right. Press Q then B to defeat the aliens (Level 1). Now, don't cheat by pressing "complete" or "done" without defeating the aliens. Please! There are four levels, each one a bit harder than the one before. Ready, set, play!
I came up with the idea when I had some extra time in the computer lab, and, when I got home, I got into really doing it!
