I liked the game, but I don't know how much it's concept is original. I remember seeing this in "Dark Echo".

My first inspiration was actually a game named "Echo: First Location". I wanted my game to have plants and walls that glow when reacting to the sounds, and to be more focused on the interactions with the monsters. But since I started late, I could only implement one monster, and I gave up the light-based stuff. I guess that's why it ended up looking a lot like Dark Echo 😅
