Thank you for the thorough review!! Boosting through the walls with the speaker and the hiding spots are very good ideas! 100%, when I make more levels, they will be things to consider when making them.
Im mainly an artist, so I wanted to do the best I can on that end to make things appealing for the player in some way or form. I'm happy to hear that part was great for you.
I also tried my best to convey ominous dread (also thank you for the compliment on this, and from a horror fan no less :D). You don't know how much your review means to me! Thank you!
