In my Computing Groups in Year 5 and 6, we have been making Scratch games. Scratch is a free programming language and editor that you can do at home. I have included a link to create a free account in this post. Also in this post are some tutorials that you can follow that will teach you how to do exciting and fun things with Scratch.
If you want to make your own game but need to learn how to do specific things, these might help:
* These code cards will show you step by step instructions on how to produce code for a variety of actions.
* This link will show you how to create a jumping character. JUMP
* How to make falling objects.
