I just tried it and it was pretty interesting. Maybe since I haven't played many dating sim games, it felt kinda prolonged at the start with the twins and their parents. I had trouble following the flow of the conversations, there could be a better indication like dimming the other characters while one is talking. I also had some issues with the music, it stopped abruptly or would skip parts.
But I liked the story, it's engaging. The art and the music are great! I'm looking forward to the full release!
I can give more feedback if you want.
