A fun game where you go in search of blueprints, whose elements seem to float in the air in 3D. You can only see the entire blueprint from a certain angle. That's why you have to keep the drawing in exactly the right angle, really fun playing! You can play this game in the 'relax' and 'hard' mode.
With the mouse you can change the angle through which you see the drawings, so that the blueprint becomes completely visible.
