It's a good game. The market for AI art netorase games feels a bit watered down right now, but this one offers a really unique and attractive main girl which is always a plus. The style seems similar to My New Girlfriend, which is making waves in the genre, and it doesn't have any glaring flaws. For now, I'd rate this game 4/5 stars, but it could still get a lot better or a lot worse depending on how the dev continues to update the game.
I'm looking forward to seeing more of Alice and Kate though, as with 15-20 minutes of story, I'm already sold on both.
