I really enjoy this game. It was really fun and pretty challenging(though sometimes I had to think for a bit before progressing). I like the fact that the people who see you don't forget they saw you like most stealth games and the when you die too many times your forced to figure out those puzzling platforms.
And honestly, I don't know why everyone's complaining about the controls.They felt fine to me.
The only beef I had with this game is that the enemies could shoot through walls.It was very frustrating to hide behind a wall when someone saw you,only to get shot through the wall. What you should make them do is move to an area where they would be able to see you and shoot if they saw you or if they don't they keep doing what they were doing but they would be more cautious.I also didn't like the fact you couldn't swing your sword while jumping or crouching.That should definitely be something the character can do.
I would hope to see more RPG elements to a future game.When you suck blood or kill enemies then you get stronger and level up to gain more abilities.Because just jumping and swinging you sword can get pretty boring.
It should also have a store to buy new weapons and special traits.
Overall it was a pretty good game and I hope to see a sequal.
