Never done one of these before, when is the reveal? When it is 100% completed? Or are tiles revealed when they become surrounded?
Only use the palette provided (the first 32 indexes in the image palette)While you dont have to use all 32 colors, use as many as you can and polish your piece as much as possible.This palette is a good opportunity for you to polish up your AA and dithering skills.DO NOT use any other colors, including the 4 grey colors of the blank tiles.No transparency (except outside the hex tile itself).
