Azure, Indigo, Cobalt- you've really got a thing for blue, don't you?
I haven't left a comment on your game yet, since I want to play it through a few more times.
My immediate opinion is- did someone else coauthor this with you? There's a marked stylistic disconnect between the beginning of the game and the part after you meet the girl.
Also, I'm personally not a fan of the way you did the dialogue (as if it were a script, rather than a story.) If this were a VN, that's exactly how you'd write it, but in a CYOA it's distracting rather than immersive.
There's definitely potential here, which is why I want to see all the story branches before rating it.
