The stealth puzzles were annoying (and actually prevented me from completing the game when I went to replay it
).
The box puzzles were time-consuming rather than in any way challenging.
You find an item you can pick up, and, unsurprisingly, you get to use it in the next room. This happens
so often.
The newspaper-under-door puzzle
.
It's not a bad game, but it's significantly worse than the previous two. And. before anyone else considers ranting on the matter, I didn't actually mind the move to 3D or the direct-control interface (but then I used a gamepad).
