When the squares touch the black bar, click the number on the keyboard that's on the square. Survive for as long as you can! :D I thought this was gonna be a quick project, but two hours later, I'm still not done. Edit: You know what, I'm gonna share it anyway. There are some glitches, but who cares, the game works. Tips: If you're going for score, pop the square just before it reaches the DEATH ZONE because more time'll have elapsed by then, allowing for more points! Tips: By FAR the most effective strategy is... Mashing the 1 2 3 and 4 buttons as fast as possible. I'm not joking.
