Use the arrow keys to move around the map. Driving also uses the arrow keys. The W, A, S, D keys DO NOT function. You can save your projects by loading a save code that can be copied and then pasted into digital storage of your own (not in comments). The code may be too long to paste in comments. When you revisit the game you can copy your save code from your storage and paste it into the load button. The save and load buttons can be found on the right bottom of the screen.
Turbowarp is a great option if you want the best experience. You can create roads, a racetrack, and even drive on it! This game simulates creating roads and highways that gets you to your destinations.
