A very good stealth game. The story is pretty straight forward. The presentation of the UI is very in-tuned with the aesthetic of the game. Graphics might put some people off, it was alright for me. Probably aesthetic choice.
Gameplay is actually really really good fun, regardless of playstyle. The level design is quite alright, designed perfectly for any playstyle, encouraging playstyle experimentation. Level design is varied and unique between levels also.
