Thank you very much for your detailed reply. You've already been replying to a lot of comments, don't worry about it. :)
This reply is mostly to come back to what I had put under the spoiler tag. It's specifically about the attachment with the singing and the screen blinking. I don't know how long the clip actually took, but I was startled a bit. So I believe I just pressed Window key to get out of the game and turned the volume down, not sure anymore. There are some games I cannot play for this reason, but I know my limits. Anyway I'm doing fine. Your warning is sufficient and I imagine it doesn't make sense to say where these appear as a new player could not understand it either way.
