So far I've played, it was okay, I actually liked the puzzles you had in that cave, maybe with the exception of that extremely long box puzzle, but I just can't play anymore, I hate sneaking, and I hate dying, so this long sneaking thing at the castle, it has just made me not want to play anymore..
It was horrible enough with those small quick "react quickly" scenes, like the car. Honestly, did anyone manage that one on the first try?
Edit: oh, and I can tell you how you get those boxers..
