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
Every kind of gate side by side. Switches A (left) and B (right) are bound to all seven gates, and each gate has a display of its color above it. Click the switches and watch which displays light up.
Control panel
Block outlines are not drawn on very large builds so everything stays fast. You can still select a block by clicking it.
