I'm not sure if it's a good idea to post an opinion on a game that covers such topic. So you don't have to pay attention to it if you don't want to:)
But in case you'd like an honest feedback, here it is: background images look nice. They really bring the 90-s atmosphere. Also interesting to see what a different country looks like.
Mika's sprite is very cute:)
And I enjoyed cheerful anime music:)
I have to mention very heavy writing. Reminded me of "The Letter", a different Filipino VN. The language seems unnatural and is full of mistakes. Maybe using simpler words and grammar would be better?
As for the story, it could easily be condensed into fewer chapters. There's a lot of text where nothing is going on.
Although story idea is interesting!
