Plan

This is what I need to do:

1. Check that the software works and is not too hard for me
2. Change the playing field to the shape I want
3. Change the colour of the field to light blue
4. Put in the teleporters
5. Add all the walls
   
6. Add the doors and keys
7. Add the extras
8. Test the game
9. Fix any problems
10. Save and publish the game
11. Give the game a title
12. Get three of my friends to test and review my game
13. Reflect on my game

The very first thing I have to do is to check the software.
