My first impression for this game was horrible. OMG, I can change directions during jumping. What did I bought? I didn't want Super Mario. Still I say the controls are horrible. I can't jump onto the floor between two pieces of furniture, because Styx grabs the edge automatically. Though if I want to escape on a balcony, it is extremely hard to jump off and grab the ledge.
Saying that I just kept playing on, because this game is just a gem amongst the other stealth games. The clone mechanism is unique. The story is outstanding. And no, this is not an action game, you will need patience to face foes who are double the size of you.
