I found him! I missed some background music here; the sounds where OK. I wish I could move the blocks faster. I think you did this because you wanted to show that they are big and heavy, but as there are no other blocks in the game it feels like a drag, somehow. The puzzle we OK; not as hard as it could get :-)
I really couldn't figure out how to run it after installing pygame and I don't have the patience, sorry you should research into building it into an executable.
