God dammit Shirokoi, you've make a story so gripping, with such memorable characters that I'm actually considering buying those plush stickers so I can put them on my laptop (it would be nice if Euca and Sissel had separate stickers but I'd be lying if I said they weren't cute)
After finishing Sissel's route my only real criticism is that the phrases, "let out a breath he didn't know he was holding" and, "Knuckles turned white" are repeated frequently enough that I started to notice how often they get used. But that's barely even a nitpick considering that the rest of the writing is fantastic. Other than that the rest of my nitpicks are barely worth mentioning, and I imagine that they'll be fixed in future updates.
Also the fact that you're selling this game FOR FREE is downright criminal given the level of quality. Once this game is finished you better be selling it for what its worth or so help me god I will buy a million stickers to make up for the cost lmao.
(PS: Another visual novel called Mice Tea has a really cool feature where you can look at a flow chart of every route and major decision in the menu, and chose to jump in at those major decisions in order to experience every route to its fullest without needing to make a new save whenever you need to make a choice. I think adding something like that would be a huge quality of life change)
