First of all i'm really impressed by the graphics and Sounddesign. In that regard it is a great experience, but i'd moreso think that this would be more of an interactive movie than a game.
Every interaction is followed by a minutes long blurry camera animation after the train section, which was fine the first time, but got annoying later on. This paired with the extremely dark environment and slow walking (which makes sense in terms of the environment) was not a great experience, it felt like walking through a sticky mud. You press interaction, watch a blurry animation and high pitched sounds and i've got a bit of a headache to be honest :( The Animations themselves are well made though.
The Story has potential since it starts off in a Train and you get transported onto a research planet and there's endless possibilities of what could be happening there, it makes you wonder what is going to happen. Hope some of what i said is valuable.
Wish you good luck and good work.
