As a big fan of Silent Hill games, here's my hones feedback after playing this game.
What I personally liked is the sound design! As soon as I heard the menu sound I knew what this all was about. The puzzles weren't hard but still pretty fun. The level design, and camera angles are amazing! However I had some problems playing your game.
First and most noticeable are the controls. After switching angles i felt very confusing to walk in the right direction. Fighting suffers for the same reason, sometimes you just struggle with proper positioning of you character. Maybe if You'd add gamepad controls, it would make it better.
Also I had a problem at the room right after the first save, where I'd go somewhere out of screen, and just stuck. I can hear step sounds, even if I'm idle in this case. I can't return and had to restart the game two times.
Enemy AI is also very weird. Enemies would start attacking you, then run away, then come back. Maybe it is intentional. I actually have no idea how to do enemy ai, let's be honest, I'm very new to gem dev, and still learning, though .
Anyway, I don't know if you're planning on developing this game, but I think that it has a great potential to become a very solid game, with some changes, bug fixes and maybe a big expansion! All in all great game and You made an amazing job!!
