Interesting story and characters so far, looking forward to future updates! Another game I'll be following with great interest!
Noticed a few things though:
The volume options don't work at all (Or if they do they didn't work for me). No matter what notch I clicked it wouldn't lower. The other options work and highlighted what button I was looking to press but Volume wouldn't.
The backlog doesn't track very well. The times I checked it because I wanted to re-read something I found it waaaay back in the scene and I had to do a lot of scrolling to get where I wanted. Would be nice if I could use mouse wheel to go back and forward like other VN's.
The scroll bar for the backlog was difficult to notice, I didn't think there was one until I finally spotted it. It also seems that if you click and drag it to where you want it though you end up closing the backlog once you stop holding down left click.
