I have it on my shelf and I have yet to really read it, as I gotta finish my other book first! I did read a few pages and I don't know if I was tired that day but I was sorta confused as to what was even going on, though it was a while ago so I can't even remember if that's totally accurate.
For me, I definitely should stay away from people straight up telling me what the book is about, cause that will just confuse me more when I read it. I would rather just go in with no expectations. Although I did watch a full breakdown of that DOOM map, myhouse.wad on YouTube, soooo yeah.
I'm wondering what you think about it so far!
