Heya! I am one of the testers for this game, and former friend of the developer! I'm here to add some things myself, and my own thoughts...
This was an amazing start for someone who just started on working with Unreal Engine. Choosing papers in order to see what your pen pal will respond with, and the atmosphere gives a feeling of dread for sure... It's indescribable!
For those who see this game/and or comment, please give it a play! Your pen buddy is waiting for ya on the other side...
