Overall a fairly pleasing playthrough
Visually stunning and contains interesting environments and challenging gameplay. Custom content is also used to a great extent.
The mood the mod is trying to sell is perfectly done through environments

However I had a few personal issues with it, mostly being with the gameplay.
Some gameplay elements (such as using keys to open doors)
The platforming areas were also a bit of a ballache
The pacing of the horror was also quite off, meaning that most of the scary elements within the mod were underwhelming and anticlimactic
There was one scary part near the end that was extremely similar to one used in Nightmare House 2. It works at scaring the player but some may not be impressed with the fact that the two scares from both games are practically identical.

The shooting parts of the game were generally enjoyable with great battle pacing and resupply. The AI could be better implemented in some fights but was sufficient in general

Overall it's a pleasing playthrough, worth a download but not without it's issues
