Absolutely wonderful experience, easily one of my new favourite visual novels. I loved how it played out as a conversation, it made the choices so much more meaningful and really made me feel like I really got to know the 'monster'. You've managed to create such a beautiful atmosphere with the art and music, and I love all the unique option names (and hitting V was a hilarious little option). I was a little surprised to see the game had 9 endings to find despite the short run time, but each of them fit really well into the story and I loved replaying the game to get all of them (got the true ending on the first try and it was so heartwarming). Overall I had a lot of fun with this game and I have no doubt I'll be returning to it again.
P.S. I've gotten all of the endings but there's one picture I just cannot find. Third row down, second from the right. Any hints you can offer?
