Just finished playing through it for V2 and I have to say, I am in love with the concept of liminality, and this helps to encapsulate that feeling.
I found exploring the different environments, both older and the newer additions both relaxing and anxiety inducing as I didn't know what to expect, especially with the Shadow people. I remember experiencing one in the locker room/ bathroom stage and one in the mall portion but with this version, didn't know if any others have been added and it took my daughter to get me to notice a few of the newer ones.
Great atmosphere, and the different stages strewn throughout were wonderful so far and provided a great variety.
In terms of features that I would recommend, especially coming from one who experiences motion sickness easily, I think a FOV slider and the option to have a floating crosshair would assist greatly, as well as the ability to turn down the graininess/ motion blur if possible.
The framerate was decent but it did jump periodically if I moved the mouse too quickly.
Overall, very well done and I look forward to V3 or even the final concept.
