I don't play much otome games, but I'm an avid VN fan. This was an interesting story. The struggle of pursuing your aspirations while balancing your responsibilities is a theme most people can relate to at its core.
I feel the choices don't have that much weight however, I've replayed a couple of times with different combinations of choices but the story still progresses the same. And by the time I had to choose a boy at the end, it felt so inconsequential with the chosen boy scene only lasting a few sentences.
Still, it's apparent a lot of love and care went into this game, as seen in the art, dialogue, and music. The character designs in particular were really well done. Was trying to brute force my way for the Gem ending haha. Maybe with more time (without the 3 day limitation) you could have designed specified routes for each of the male characters while still following the core story in parallel.
Overall, it was a neat experience and can't wait to see you guys improve in future games~
