Where do I even begin with this one...it's beautiful, and simply fantastic. Right away I could sense the love and passion that's been put into this game, the areas of the game look fantastic, and the music used it suites the style well.
The atmosphere is set up perfectly here, right off the bat you feel a sense of unease being in a forest at night, however you're accompanied by your friends but that comfort is quickly stripped away from you as you have to venture out into the forest in search of your companions. The forest is mysterious, dark and creepy but the real show happens once you make it to the train. The train cars are beautifully detailed inside and give you a sense of dread as you explore and uncover the mysteries that surround it.
The game has a great cast of characters that you slowly get to know over the course of the game, mostly through notes and drawings but sometimes through really old flashbacks that set the tone for the world that's being built up.
Despite only being a demo, I can tell that this game is going to be fantastic once complete. I hope you don't mind but I've started a let's play series of the game's demo on my channel.
Cheers and best wishes to you.
