This was a thrilling read! As someone who's played the original UAN, it was interesting and also heart-breaking to see how Nick's character has evolved between the games. I loved all the detailed descriptions of his appearance and mannerisms and everything - together with the very expressive sprites he really comes across like a real person. The eerie music really helps, too!
I also liked the newly introduced characters a lot. It was smart to have someone other than Nick as the narrator - we got to see what a "normal" person sees when they interact with him. I mean, I already knew that man is a mess, but it was honestly scary to see just how big a mess he is (/has become).
I can't wait for your next game! I hope you all know you're making amazing stuff.
