Good Game! Author defiantly have imagination, and renders one of best that I saw. More of that some of them pretty well animated.
But, without incest patch some of dialogs sound ridiculous. Phrases like "you my little/older friend". Also game (in no incest version) should have some normal backstory of school guy living with not his family.
I can propose make him part of some exchange program. It will fit perfectly and can help with unusual interest from schoolmates and some other person’s motivation. For example, teacher can be racist with some anti-globalization politics.
If anyone can, send it to ICSTOR, please. I know that final Judges will be Patrons and ICSTOR itself, but I think that really good improvement idea.
