Press the green flag to begin Use the arrow keys to move the claw and the space bar to pull
The goal is to pull the cat using the claw. So in theory you follow the instructions to pull the cat. If you miss you get to try again. If you get pull the cat, you win and the game stops because of the "stop all" block under sprite 2. But what happens is that after you win, you can still press the space bar and pull nothing.
