(Sorry for my english, it's not my mother language)
I'm a big Silent Hill 1 lover. After beating it so many times, i started searching for mods or something that could make it a little different. I'm really glad that i found this game inspired on it, because it's really good! It really has the atmosphere that an horror game should have, as well as that uneasy feeling that makes you feel when you play it.
In horror games (and in general) i always pick the hardest difficulties. I like the challenge. And so i did in this game. But i can't say that i liked, because before i could encounter my first enemy i died because of falling in the pits. Frustrated, i changed both action and riddle difficulty to easy. I think the pit thing also happened in SH3, but there weren't so many and camera angles worked different in that game, so it didn't bother me. I must say that it's a shame, because dying because a monster hits too hard, because you weren't too careful or because you didn't heal when you had to is ok for me. But dying because i didn't see a pit in the dark and having to restart is not. It's just my opinion, but i'd love to experience the hard difficulty action without having to worry about pits in a game that i never thinked about it as a platformer when i saw it on youtube. Again, it's just my opinion and i hope that my feedback helps.
As for the puzzle in easy mode, i liked it. I liked that it doesn't give you the answer right away, like finding a paper with 3 numbers and there you go, enter the code. So i'm going to replay the game to see the normal/hard riddles!
Congratulations on making such a great demo and i really hope that the development of the game goes well! The best for you!
