Instructions: Use the left and right arrows to move Space bar to shoot You start out with 10 lives, if you shoot one you gain 1 point but if you bump into one you lose a life. If you shoot an asteroid with a "10" on it, you gain 10 points instead of the regular 1. If you shoot an asteroid with a "1" on it, you gain 1 bonus life (bumping into this asteroid will not result in the loss of a life) If you shoot an asteroid with a question mark on it, you will be asked a question. If you get that question right, you gain 20 points. If you lose all of your lives or survive for the full 60 seconds, you will be brought to the answer key. Thank you for playing, and good luck!
