Great Visual Novel!
I really felt for the protagonist. Alyx is so incredibly adorable that you just want to give him a hug in every scene. Coincidentally, a guy I know and like has a lot of similiarities to him, including an almost identical name...so I'm maybe a bit biased. Nevertheless, Alyx has earned a spot as one of my favorite VN protagonists.
The artworks are cute and the expression do a great job at conveying the emotions the characters are having at the moment.
The story is told in a way that really touched me. Without a few elements it would be a typical slice-of-life/coming-of-age story, but I was way more entertained than these kind of stories usually do. The chat room messages including emojis were a nice addition as well and seemed pretty authentic.
Solid BGM as well.
What really surprised me was the animated background in the main menu. That is something you definitely don't see every day.
Some technical stuff was a bit of a letdown. While the text moves across the screen, you can see the markup tags for text, before it is rendered in italic. Not sure if that's a usual problem of your engine, but it would be great if you could fix that.
Also, after reaching a dead end and the true ending, the game froze both times and wouldn't accept anymore inputs, so I had to quit it with the task manager. That was a bit frustrating.
Still, I'm very impressed with this VN. Can't wait to see the full version!
