In this project you make cities (hence the name). To make the cities you use the number keys to change the type of building or road needed. There is also one secret for Doctor Who fans to find. This is on a different key. Use the up and down arrows to change size, and the left and right arrows to rotate. Press 'space' to stamp. Press 'c' or the green flag to clear or restart. The buildings and their numbers are as shown below: 0 - park 1 - house 2 - garden 3 - road 4 - path 5 - flats 6 - crossroads 7 - skyscraper 8 - bank 9 - cinema (unknown key) - TARDIS Enjoy making your city.
