Took me just over 30 mins, including incapacitating all people and finding all loot.

Fairly straightforward mansion mission with no surprises or novel elements.

It starts (and ends) with a hedge maze and there's a reasonably easy cheat to avoid some of that (no, you can't hack through using your sword).

Textures were good, everything worked OK.

I would have finished quicker but for me being confused with one of the objectives (gem collecting).

You found all the loot? I'm stuck at just 100 below the total. None of the other items seemed all that hard to find so maybe there's just one incredibly difficult piece to find.

Sometimes it can be easy to simply stumble onto a difficult to find bit of loot. I rarely find all of it so I think I just got lucky.

Where I did struggle was to wander around for ages looking for loot only to find that one of the objectives was also loot.
