Excellent game! As a block-pushing-futurist I love that you built such an interesting take on it, using the skeletons to complete the puzzles. It all looks so good and cohesive too, I like the additional mechanics explained within the later levels as graphics. And the photos as a bonus challenge is a nice touch. Coming up with puzzles within an engine can always be tough, but you made some really good ones with a reasonable difficulty curve. Very impressive entry!
