Scoring Tip: Use ammo not only to escape the dilemma, but shoot in advance where the opponent is about to bounce a lot of balls, which you reflect DURING FLIGHT and makes A LOT harder for the opponent to defend. I got PWNER achievement with this strategy.
In room 5, the program said me to pick a number between 1 and 100000. I typed log100. The program says "No, I said pick a number. A NUMBER. GUESS A NUMBER, WORM." log100 equals 2. So I did pick a number between 1 and 100000. Now I can say,"I picked a number, you mere f***ing program."
