Blueprints
Blueprint from a picture
Choose what to make from it
The picture becomes pixel art made of game blocks: a wall, a floor or a relief. Build it layer by layer from the bottom up.
Pixel art settings
A stone fortress on a 44 by 44 raft: battlemented walls, four towers with roofs and flags, a marble keep with windows. The wall cannons fire with buttons F and G, and four mega thrusters move the whole castle.
Control panel
Block outlines are not drawn on very large builds so everything stays fast. You can still select a block by clicking it.
