I love the mood and setting of this story! It seems like it'll definitely take a while before there's enough content for me to feel satisfied going through it (as of now the main appeal is more just the school setting than anything about the transformation), but keep it up and I hope I'll remember this still exists in a year or so.
I felt like the character/menu buttons on the top corners weren't clearly telegraphed enough that that's what they are. It'd be nice if it told you explicitly to check them out at some point.
