The premise and atmosphere is spectacular, although needs some polish.
From the start, the player is thrown into this eerie environment with nothing but clues and subtle hints of what to do and where to go. I think the game shines best at visuals and building tension, although the sound design and overall performance is not as great. Maybe adding some "non-popular" sound effects or creating your own music can improve the overall quality. Furthermore the pacing can be improved.
Besides the issues listed above, the game has a great potential. I would definitely be interested in more improved version. Don't stop working on. Best of luck with the future developments.
