Its much more polished and well done mission compared to the recent FM's from other authors( hotel clair de lure and ashcombe house). I'm huge fan of the puzzle missions , I think the little puzzle elements should be in every mission ;) this puzzle is ok .
In my opinion the pathing of guards, narrow hallways and a lot of marble floors( and we have only 2 moss arrows) is kinda downside of the mission, but for the first FM it's really good.

Thank you for the review!

I'll keep in mind to have some easy-to-spot moss arrow locations if I have another marble heavy mission. There's a few moss arrows to be found, but they're quite hidden.
