Every square is ten meters of the real world. Zoom in until the grid of squares appears, pick a color, and click to stage pixels. Saving spends from your wallet, which refills over time.
A dashed edge marks a pixel you have staged but not saved. Saved pixels have a plain edge, and a batch you have just sent is ringed in green for a few seconds. To push everything you already own into the background while you work, turn on Dim saved pixels.
Painting on empty ground costs one pixel. Painting over someone else’s fresh work costs more, and painting over your own always costs one.
Work you leave alone for months starts to weather. Repainting it costs one pixel per square, and a landmark never weathers at all.
To copy a picture, add it as a template. At 1x size one image pixel covers one square, so a 64 pixel drawing is 640 meters of ground. Put it on the map from the Template control at the top left, then drag it into place and set its size and angle. Snapping it to the grid lands each image pixel on whole squares, which is what makes it paintable. Auto-color then takes the color the square under your pointer is supposed to be, so you can work through a template without picking colors by hand.
