Stumbled on this the other day, really glad I did. Wasn't sure what to really expect at first but I found my first play through to be really compelling. Second play through I started realizing how many and deep paths there actually were.
Funny enough my first play through I didn't encounter a single bug but on the second one they started to appear and now that I'm trying to see all paths they're definitely manifesting so a bit of flushing out still needed there.
Actually one thing I really wanted to note was how much I appreciated the phone in this. A lot of games add them and they serve for like a single situational purpose and are never used again. I really felt like I was motivated to keep checking for all the girls each day and really appreciated how much Katie required it.
Aside from the bug fixes, I think the only thing I'd really like to see is a gallery added. Both to revisit past scenes and to figure out what I'm missing. If it's in the game I unfortunately can't find it.
