I liked the game but wish there was a bit more to it! I think your tutorial gave away a bit too much, horror games are about fear (usually) and if the player knows exactly what they need to do without figuring anything out it can take away a bit of that fear.
"The tutorial told me to stand here when the monster comes and I'll be safe!" Even something sly like, "Pay Attention to the Radios" would be a bit better! You have clearly marked places on the floor too so the player should be able to figure it out! Or show you mechanics instead like the Radio in Silent Hill 1. You hear that crackling and not sure why but as you approach it a monster crashes through the glass!
But really good effort I did enjoy it :)
