Brick Box: an isometric pixel brick builder

A green baseplate, 24 studs square, seen from an angle. Pick a piece and a color, then put it on the baseplate; it snaps onto the tallest studs beneath it. With a keyboard, focus the baseplate and use the arrow keys to move the cursor, Enter to place, Delete to remove; the full list of keys is under Keys. Box mode tips out a themed box of random pieces and you can only build with what's in it. Little people wander about, chimneys smoke, and at night see-through pieces light up like windows. Share saves your whole build in a link.
