I am OBSESSED with the use of the theme in this one! It was so cleverly done. I really enjoyed the exposition around the cuckoo and how that then translated to our changeling character. The UI was also particularly beautiful, although a few of the lines were too long for the text box. I loved the soundtrack selected, it set the vibe so well. Overall I really enjoyed the game, I feel like it was so cleverly done and a very effectie narrative done in a concise story, which is so hard to do. There's a lot of world building and understanding of how things worked packed in, and it doesn't bog the story down. WELL DONE!
I did get just a few errors, all of which I think were already mentioned, and then in the black swan ending I got (SUPER cool btw!) there was no sprites for a while, which I'm unsure if that was intentional or not, but nothing game breaking!
