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 sailing ship 66 blocks long: three masts, nine sails made of 0.2-thick fabric, a stern castle with the helmsman. Sixteen cannons fire in a rolling volley: button F starts a chain of 0.2 s delays.
Control panel
Block outlines are not drawn on very large builds so everything stays fast. You can still select a block by clicking it.
