I'm working through playing all your visual novels. I just finished both endings for Leo's route as my first play through and wow. Each option is incredibly sad, but also unavoidable. I enjoyed them both immensely and after getting the more negative ending for Leo first I was really appreciative of the alternative, even though it still really hurt. Thanks so much for making such great stories and beautiful artwork to go along with them. This story has challenged me more emotionally than I was quite prepared for. I can't wait to dive back in to try a different route, get closer to other friends in the group and hopefully learn more about the mystery of Echo.
Possible spoiler for Adastra and Khemia:
I especially appreciate how the concept of the other that we see in Adastra is already present in this earlier work. How it manifests across the universe in small pieces and larger concentrations plays out really directly here. Brian's arc and his experience in the mine was especially chilling. I don't know if I've ever hated a character as much as him and been so satisfied with the conclusion of their story. The ways in which the other gets its tendrils into him and appears to him in different ways is not only disturbing and moving, but probably not too far off from real life.
