Arrows to move as usual, avoid the cat. Get 100 points OR have 0 time left to win. If time runs out, you win, not lose! Have 0 lives or less to lose. Yes, 0 or less. It happened in testing. I got to -2 lives because the loss/win script also counts down the time left counter, so I lost 3 times in 1 second! The game isn't unfair.
