Hiya!
So to start off, I'm really enjoying the GUI. The tones of blue, the ribbon header backgrounds, the half-tone fade of the menu-- super clean and appealing. The button SFX gives it a "video game like" feel(? sounds like a tetris block landing). Text is crisp and everything is perfectly readable. I also really prefer menus being on the right so you have my appreciation.
In the "...When will you two become boyfriend and girlfriend?" convo, the way Anna protests sounds a bit unnatural for me. "That's SO not true..." is in response to Elena saying you and Anna get along so well, then follows up with the bf-gf question and a pause from Ryne. Perhaps "We don't get along THAT well. Mom!! Stop making stuff up!" would flow a bit better in that structure. It highlights what Elena first said and maintains what you already have down. On my first read, I assumed her retort was to the question, not the "getting along" part.
Overall, I think there could be more natural pauses and shorter ways to write some of the sentences. Something like sentence rhythm(?) is what I'm getting at.
The music is really good! Lots of energy and pairs well with the scenario. My only complaint is on some tracks, the synth piano(?) is way too powerful at times. Like vibrating in my eardrums too loud (not using head/earphones). I don't think this will be too much of a problem, but it could be a bit bothersome for longer scenes.
Now for the routes! I found that Anna and Mikaela are similar in some ways. Both are predictable in how they carry themselves in regards to their personality. I'm interested in how they'll change personalities as you become more familiar. Anna's self-esteem issues and relationship with mom/Cafe Memroia vs Mikaela's anger issues and deal with Julia (other than jealousy/envy?). I prefer Anna, but I'm interested in what direction Mikaela's story will lead to.
I haven't played the first game so I apologize if there's something off about my feedback. As a standalone, it works well even though I wasn't properly acquainted with the characters. I would like to know if the first game has romance routes or all the routes simply converge and transition to this sequel. The obvious answer would be to play the game and find out for myself, but I can only make time for demos/short games at the moment
Anyways, you did a good job! Keep it up and I look forward to more releases. (P.S. no bugs found!)
