Great game! I loved the concept and the puzzles were really good. And the music is fantastic, I love how it evolves as the game progresses. I found a bug in lvl 19 (don't know if it happens in other levels), in which, if you leave a dead body on the middle button, and then you try to posses another body while you are standing over it, but you don't, it deactivates and doesn't recognize that there's still the first body left.
