(Spoiler Free Review)
Wow. Oh WOW. This was an incredibly fun, intriguing, and terrifying read I must say.
I also read TCCoR19 when that was released, and I was already impressed with your horror writing then, and I'd say just in those few months you've improved greatly! I don't really know what it is, but I became much more sucked into this one, ended up reading it until like 4 am one night because I Did Not want to stop. I'd probably say the greatest thing about it is how you implemented the horror/scares, there were so many good ones in here, truly. You used the medium of a visual novel to sell them extraordinarily well. I kept trying to look slightly away when I felt something scary was about to happen, which is something I commonly did while reading Echo, so give yourself a pat on the back for that, genuinely.
One thing I said while liveblogging this for my friends was, "I love seeing passion projects made entirely by one person like this, it's inspirational to see," and I really mean that. The effort you put into this is crazy and really awesome to see, and I'm excited to see whatever you end up doing next.
