Man, this one really got to me. Once the sounds started to repeat the exact same way I started to get used to them but I REALLY didn't wanna go looking around that house because of them. Excellent use of obscuring walls, and the mechanic of having to go out to find more tapes forced me to go out into the darkness.
For your first time taking on 3D in godot, I think you did a stellar job, particularly with the audio. Great work!
