Remove the whole town?
How it works
Tap the meadow and a little house appears. Tap it again and it grows a floor. Nothing to plan, nothing to finish.
Pick a color, then tap anywhere on the grass. Tap the same house to add a floor (up to three), and once more to take it down. Houses of the same color and height that sit side by side join into a row with one long roof. The tree button plants trees. Your town is saved on this device, so you can come back and add to it. "Start over" asks before it clears anything.
