Pixel Block 3D

A yellow smiley waits under a layer of white pixel cubes. Pixel Block 3D sets a rectangular block above that picture, with empty spaces breaking up the path across the board. Progress depends on covering the buried image with the block's movement and revealing more of the face with each pass.

How to play?

Guide the block across the white cubes and move over every pixel without slipping into a gap, because a fall ends the attempt right away. Wherever the block passes, part of the smiley appears underneath, and a fully uncovered picture adds points before the next level loads.
