the dark and the music are amazing :d
Not unique, but intriguing to play.
While the ideal of light & dark in a puzzle-like gameplay has been done before, this game has taken a bit of a unique twist that makes the game very interesting a compelling to play.
The painted-in instructions may frustrate some players that may overlook it (as it does tend to blend in to the background), it one professional method to introduce the basics of the game without the annoying tutorial mode that some games force your to run through.
I had to dock a few points as this isn't a "Mee Wantee" quality indie game (that World of Goo & Alien Hominid got), but it's a quality game that most people will enjoy. Keep it up!
