Some of the puzzles are good, some okay, some really stupid.

But one thing for sure - you ARE thrilled when you find something as mundane as a longsword, or another shuriken, or a couple more normal arrows.

In a way it's a welcome change from ARPG's where "rare" items drop far more often than rarely, and more times than not the uncommon/rare drop isn't any better than what you already have.
