Thank you so much! I should probably keep it free if it's free here, but adding achievements sounds fun~ I should at least add a pause menu, I agree ahah.
Spoiler:
Noh came to the factory because of their friend who looked like Moku - but it's their first time meeting in the game. The blue eye belongs to his friend~ I think Moku and Noh develop a very close bond in Noh's ending, but I'm not sure if it's romantic or not - I guess when your bodies are together it goes beyond that? XD
I should check out the DM endings .o. I enjoyed the anime but I haven't played the game~
