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 safe full of gold that opens only when the right code is set on four switches: on, off, on, on (left to right). An AND gate checks the code, with a NOT gate after the second switch. Green display — open, red — closed.
Control panel
Block outlines are not drawn on very large builds so everything stays fast. You can still select a block by clicking it.
