Very interesting stuff. The shadow casting is neat and the ability to wear a disguise and hide is really cool. Combat felt a bit scuffed at first like sometimes the guy doesn't swing when you press the attack just the bar gets deplated but I managed to clear the first level after a couple of tries.
I faced some issues in the second level. The enemies seemed to be invisible. Not sure if that is a bug or part of the deception =D
Also there seemed to be nowhere to go except for those two entrances which I couldn't get through as if there was an invisible wall or something.
Aside from those small issues, the game is good overall and the concept is cool. Well done.
