I adore this game, I've played it on repeat for a long time even while knowing what the all routes are like so far. Though, out of them all, I'm quite sure Quinque has to be my favorite. Unum is so cute as well, he's my next favorite after Quinque. Seeing Noor and Shams made me feel like an actual proud father. But I REALLY, REALLY need Quinque content. I can barely find any content of him anywhere. I wish he'd be dateable or had his own route of sorts.
Anyways, I also really liked the puppet, pretty sure the only thing that got me hooked in Septem's route was just the puppet making themselves more noticable where in the other routes it wasn't really that big of an impact. I hope you have as much as fun making this game as I do maladaptive daydreaming about this game for hours straight, I'm looking forward to this game being done!!
