Click on the Green Flag. Then click on the scene and a rocket will launch and fly to the point you clicked, then explode.
Uploaded from Code Club's github repo 20140123. Challenges: Make rocket get smaller as it goes into the distance. Better drawing for the rocket, with its pointy end smaller to look further away from viewer. Launch the rocket from either the bottom-left or the bottom-right corner, depending which half the mouse-click was in. Make the rocket follow a curved path, tilting over as it goes. Tricky: be able to launch two (or more?) rockets at once.
