Press number keys to switch tiles. Connect the houses with roads. Every successful trip earns you 1 money. Money is required for building more roads. More houses will later spawn. Make sure not to cause any traffic jams! If you do, you can press 7 and click on cars to remove them. Tip: Try not to use too many of the normal roads (2) if two cars come in opposite directions they will be stuck there.
This project is named after Gridroad + Mini Motorways.
