Damn that was good. The concept is awesome, the puzzle are really creative, and the theme is perfectly respected.
This game is the definition of "level design". The difficulty curve was PERFECT, and the way you taught all the mechanics to the player is brilliant.
A little background music could add a little plus, but that's really my only complain.
