Scratch

Scratch is a application where you can make cool games and share them with your friends. To make your games you will use blocks. As perfect as scratch seems, it also sounds quite complicated. One of the most complicated blocks is the 'more blocks' features. When you go onto this purple block you will want to make your own block as the words draw attention and excitement. Once you click it, choose a name for your block (e.g. grow). Then you select 'define grow. If you want your character to grow, insert 'change size by 200%. Now to make it work. When space key pressed grow. Click space key and It should enlarge. That is how to use custom block.
