Not a bad idea. I'll add one in after the third episode. Need to put a replay system in first.
Just finished the chapter and I can't emphasize this enough. I hope you accept criticism, but the game introduces and mentions too many characters that you barely interact at all. There is also a "Sugi" mentioned (but never shown?) that I thought was "Suki" at first, which confused the hell out of me. It doesn't be to have anything majestic, just a model of the girl and a one line description would be enough.
This aside, I enjoyed the game (a bit too similar to Lessons in Love, but that was expected since you can clearly see the inspirations and the citations) so I will look forward next updates. Have a good work.
