Yeah I agree, it definitely gets a 10/10 from me. Decent length, huge levels, great visuals and some seriously fun stealth gameplay.
Speaking of gameplay I particularly like the whole field of view thing where you can only really see what the main character can see, it makes the stealth a lot more tense. You don't know what's waiting for you on the other side of a door until you're pressed right up against it. There's been a couple of times I've gone up to a door and pressed against it to sense what's on the other side only to see a guard reaching for the handle lol.
I like the stealth kills too. You can do them from virtually anywhere, and some of them are pretty full on lol. I was kinda surprised by how violent this game is to be honest. I don't mind at all, but with the cartoony art style it kinda caught me off guard a bit. To the point where I actually cringed a little the first time I cut a guards throat lol. I think it's just the way they clench their teeth when you start to drag the blade, it's pretty horrible :p
