I love the dark enviroment, it gives a lot of spooky vibes, specially when you try to hide in it, sound is also a great adition, but it also ruins the experience when you don't seem to be doing any noise and it still attracts Rumia .
Never expected to find Kagerou in this game, that was pretty nice.
I like when character swapped places that one time, and you need to find the Haiku somewhere else, but I had a huge problem finding the solution on it (because I'm dumb), but I never knew if I had to reset the chemistry set, so I took my time wondering about that.
Its kinda funny that you can actually keep reading something after you died xD.
