I LOVED it! Even though it took me around half an hour to clear it, you managed to cram so much into this VN! I really cared for the characters and their struggles, and the girls' story felt genuine and heartfelt. I especially liked how the ending wasn't just a simple "and they lived happily ever after", but Renko and Maribel also decided to help the people in our world who might be struggling with their identities and their new lives. It really feels like it was written by people who suffered through all that.
Both the characters and the backgrounds look amazing, and the music is really fitting! I'd love to see more Touhou VNs like yours!
