Hey, I really enjoyed playing the demo!
But I took some notes on things you might want to consider. (Don't need any change; its just my particular opinion.)
When playing the start at the parking lot, I would believe it would be interesting to use the lights to guide the direction the player has to go.
The camera drag kind of annoyed me, but I understand if it is your design choice.
At one point of the demo, you read a journal. I would prefer if it was paged instead of scrolled (because English is my second language, being able to decide when to turn the pages would be better for me).
Some scenes are too quiet; in the apartment, I can understand, but when outside, I guess you could add some immersion by adding ambient sounds.
The click range is kind of too low for me; I have to get to close to the door to open it.
And about the loading screens, I believe you could make it without loading screens (I know it takes some time to do so, but the game would be much more fluid with seamless transitions).
But, having said all that, I really enjoyed playing the demo, and I'm looking forward to playing more!
