Still early days on this but a coupls of comments I wanted to make.
1) during the first nightmare/snowstorm sequence, coming down the stairs there is no snow visible through the window. And in the next image where you see the snowstorm, it only appears in the right window, not the left.
2) The screen distortions during this section might be a little much, Im assuming that they are supposed to happen and enhance the creepy mood, but to be honest I was worried the graphics chip might be melting the first time I saw it. Also, not sure if it applies here, but given the flickering nature of the distortion you may want to consider an epilepsy warning or something. (I dont have epilepsy so I dont know if this would trigger it, but better safe than sorry I would have thought.)
3) I know you can swipe up to get the menu, but an icon on the top left toolbar might be useful as well.
Other than thqt, enjoying it so far. Looking forward to the rest.
