Hey hey! Thanks for playing through the game :3 I'm glad you enjoyed it :D
If that is an English expression, I haven't heard it before, but I still get what you mean :3 that's actually a pretty cool way of putting it, haha. And you don't need to apologise at all x3 My eyes aren't bleeding, haha.
To answer your question, I guess I should put it under a spoiler.
SPOILER
Okay, so, that voice is a character from my very first game, Solipsism Reigns, but the character has his own story which will slowly unfold across some of the games that I release over time :3 You get to hear much more from him in Solipsism Reigns. His appearance in Apartment No.9 is pretty brief in comparison. While he technically doesn't have a name yet, I always referred to him as 'The Architect' when writing scripts, and some people have affectionately given him the nickname, Archie :3
