As a Limbo fan (100% achievements on Steam) I see were your inspiration came from.
Your game is very entertaining. Short, but it's a game jam.
I found some issues mention by other users, like "killing" the clone (falls down) and had to restart the whole game.
But would be nice a few more levels to explore the game, and combine the powers of the souls for solving puzzles.
Great job! Congratulations!
