I second Matt's review wholeheartedly. The whole level is intriguing in visuals, acustics, atmosphere and layout.

The puzzles are only wayfinding-related but I felt clever with every hidden entry and dark alcove I found.

Resources are very scarce but sufficiently balanced.

There were a bit too many locks to pick that had just nothing of interest behind them (but a sliver of loot) and that felt more like filler than substantial content.

Now comes the big one...

Without spoiling anything fun: There is SO MUCH stuff hidden behind destroyable objects that each take 8 strikes with the dagger to destroy and there seems to be no hint to any of these secrets nooks and crannies around whatsoever. This makes what seems to be an absolute banger of a FM to a chore as you'll get stuck so many times without knowing what to do to proceed, it's just sad.

Do yourself a favor and use the walkthrough as soon as you get stuck.
