Hehe, well, I mean I was hoping that those bits of UI that you're referring to would be voiced as well so that they'd be even creepier :P But yeah, hopefully, they will be at some point!
I still haven't had a chance to write up a walkthrough yet, but I guess once it's up, you'll be able to check and see if you managed to find all the endings currently available in the demo :3 I can't actually remember how many there are xD In the full version, there will be a lot more anyhow! Glad you had fun with it :3
