Very original take on the theme. Unexpectedly... Mathematical. And even more unexpectedly fun!
I really like the narration - it's good to hear a human voice among all these effects and instruments. Love the death skull graphic. All the graphics, in fact are very well done. A few points of criticism though - when the objects you're comparing are all crates - it's really easy to confuse the two - maybe have one with a different outline, or have a few square objects such as a TV, or a toybox, or a generic definitelly not Scandinavian building brick (TM)? Another thing - in lvl13 to break the glass floor, you have to compare the two boxes, stacking the increase in size on one, which seems like a bit of a bug exploit. Not sure if it was intentional, and it kind of brings back the problem of distinguishing between object A and object B. The jumping feels surprisingly heavy and yet still a tiny bit floaty, though that's a smaller issue.
