This was fun! I enjoyed the different ways of obtaining puzzle pieces to get to the next part. The movement was smooth and the animations were pretty snappy, too. Decent interpretation of the theme, as I found myself looking for signs to the next floor number, but could have been stronger. I never saw the room in the last screenshot, so I played a second time to see if I missed something, but still got the same ending. I was pleasantly surprised to find that the floor numbers changed, though!
Nice work!
