Think others have said all there is to; this is really a great game. You've nailed the visuals and sounds and also the feel of everything. It's super immersive and really scary.
An improvement over previous games is that, this is more straightforward and easier to figure out what to do next!
The only thing I think can be improved is that the flashing lights don't really work well with the sudden change in hand movement that the character does whenever there are enemies incoming, it feels like a bit much, confusing and feels unfair.
Other than that, it was a great experience!
