I only played a little bit of the game (4 endings so far) but it is an absolutely enjoyable experience, the visual filter are nicely used, the sound design is on point when using headphones, the tense atmosphere grabs you from the beginning and never let go.
The story unfolds slowly and nicely, I wish I could say more but as I mention I am yet to complete the game, I'll probably update this review after I play the rest in a couple of days but so far I adore what I have played.

Edit after getting all endings
-------------------------------
Golly was that a wild ride, every thing I say stands and it even improves, first I will start with the "bad" parts because there is not a lot of them; It was mostly performance issues that lagged the game and upped my CPU temps but the developer swiftly fixed them.
I had some issues transferring save files between versions but that is more my inability to replace files than a problem with the game itself, and lastly the final problem with the game is that there is not more of it!
Now for the good stuff, the game has incredible sound design that reminds me of Silent Hill 4: The Room, using headphones is really recommended and enhances the experience.
I cannot stress enough how good the story pieces together and all the endings have something to offer to unveil the plot of the game, it also includes some excellent Visual Novel parts and classic RPGmaker chase scenes that put the fear of god in you.
I could write pages of why you should play this game but I'll put it simply, is a good game with an interesting plot and fun gameplay, it is also FREE, there is no reason not to try it.
Keep up the good work!
