and I like to think that DarkDragon (the author) did that, ultimately came to the conclusion they must try to push the limits even beyond anyone could have ever imagined - and Avoiding Mistrust was the end result of that almost scientific experiment.
The other option I can imagine is DarkDragon just genuinely liked picking locks a lot (for some reason). Either way - and jokes aside - the amount of locks this mission has is... 𝘣𝘦𝘺𝘰𝘯𝘥 𝘳𝘦𝘢𝘭.
Since the 'Normal' difficulty has a bug which prevents any type of saves being done, the player either chooses another difficulty, or enables the uninentional Ironman mode. Since there is an overwhelming amount of loot in this mission (10k is the max), and the map is quite huge, I'd say it's worth to do the former.
Especially since the mass of same looking hallways and bedrooms quickly become tedious, there is not really much environmental story telling or interestingly implemented areas you can stop and appreciate (only a few exceptions, one of them was the pans set up under the leaky pipes in the basement area, I liked that small detail a lot). Though I admit, the sometimes otherwordly huge spaces combined with the insane amount of locks - and the otherwise well used ambience tracks - create an interesting, somewhat dreamlike experience. Not necessarily in a good way though (like when you'd say the same about a Lynch movie, for example). It's more like a "what am I doing and how did I get here?" kind of ambivalent, almost transcendental experience. Speaking of the visuals, the mission has a few of custom looking textures I liked a lot.

To sum it up, even though I can see that a lot of effort went into this mission, it's quite odd. On one hand it has awkward level layout, questionable amount and use of locks (most of the time chests with even the most complex lockes include only 25-50 gold worth of loot ), a few technical issues (the rope arrow is practically useless, one uncollectable loot, the bug with the Normal difficulty), but... On the other hand it does have a few interesting moments, and aspects I can imagine some could enjoy. Like, the amount of everything this mission has. The amount of loot, guards, rooms, locks, etc. I don't really like quantity over quality kind of contents, but if you don't mind that at all - give this mission a try.
