How do you rate Requiem? (or until now)

[Umbra]

Demo 8
Overture: 9
Black Plague: 7
Requiem: 4

Requiem is not bad but this is the worst part of the series

Why flashlight have endless battery? Where are any anamy? I expect puzzles would be more difficult but I have problem only in one place... I have only one scary moment in the beginning, then I feel only furstration... First 2 levels are the best but then... Oh, one more question: why it too NOISY?? I have a headache after end...

And for what those artefacts again? Alternativ ending?
