This game is just awesome! I got a little obsessed with it and got all the endings in a couple of days (thanks for the guide btw :p). The art is great, and all the characters are really interesting! Especially Reggie, even if he's a little out there :D!
Mary is the best though, she's such a pure cinnamon roll! Because of her the game felt really... sincere, I guess? Some scenes just made you want to hug her and tell her everything will be ok. After all the danger and loss Mary went through, the true ending gave a nice sense of closure. Like everything will be alright, even if it won't be the same.
I also loved the mystery, though even after the true ending some questions were left unanswered. (I think I understand what's happening with Reggie, but other stuff in his route was really confusing)
I hope that you'll show us more of this world in your future games!
