I actually really enjoyed the graphics, I thought they added to the creepiness of the whole thing. The open-endedness was what bothered me the most. I like some finality in my games. The cloning mechanic was just perfect.
The game was good, I only did not like the graphics, there is too much bump on every model in the game. Gameplay mechanics were interesting though. If you liked it I can recommend "The Fall". The gameplay is quite different but the ambiance is close to The Swapper.
