Honestly, I loved the puzzle haha! I failed about 3 times trying to figure it out but because of how Emerson reacted every time I failed, I never felt like it was a bad thing. It was more engaging and it felt more like I was playing a game vs reading a VN. The uniqueness of this VN I think comes from the fact that Chapter 1 felt so interactive. I liked that the puzzle wasn't too easy and actually required you to think and the hints weren't super obvious either. Just enough to give you a little push in figuring it out.
