Creating a game - Moneycopter

Let us create a fun game in scratch. In this game there is a Helicopter flying at the upper portion of the game window. Left- Right-Left all the time. 

There is the Scratch Cat that can move with the Left and the Right Arrow keys. Press Spacebar and it will throw a stone upwards. If that stone hits the Helicopter, then a thud noise will be heard and a bundle of notes drops from the helicopter. Collect that bundle. Don't let it fall on the ground. The game lasts only for 30 seconds. Collect as many millions as you can. 

You can see all the coding used in this game on the project's homepage on MIT's scratch website on the link below.
