The concept and idea of this one are by far the best! And I love the visuals :)
Really cool idea, and it was fun to play! Would like to see it getting some polish, with maybe new levels, and complicated scenarios (maybe having the enemies go in special paths to make it harder to avoid your shadow, or maybe the shadows still can kill enemies which would be an asset for the player to use in order to beat the enemies in more difficult levels...)
Well done! :)
