Yo, this game is amazing! The idea of it being linear really made me hesitate at first, but the execution is so well done that I completely forgot about that fact.
I little recommendation, would be nice in the future to see some slight drama in the relations (like small danger of getting broken apart). Right now feels way too perfect most of the time, a few struggles could make it more interesting. For example, Lily can misunderstand something, thinking that you lied to her and gets sad, now you need help from other friends to show her the truth and not only return to normal, but make the bond even deeper and stronger.
Great game, eagerly waiting for more, I think I'll buy the next patreon release when it comes out.
