Among similar games with texting on the phone, I liked this one the most. I'm usually skeptical about the heavy use of emojis, but in this game, I must admit, the author used them very skillfully, making the text more expressive and interesting to read. Keep up the good work, dev! The art is really good and quite sexy, my thumbs up as well. The variety of routes is a great addition to the list of advantages of the game. Most games don't even have half of the variety that we have here. However, some of the routes are a bit underwhelming. It would be more satisfying if the happy endings also rewarded the player with "content" instead of giving you a final message telling you that everything ended well. It actually feels like a bad ending. You don't get anything after reaching such an ending, as well as in bad endings with blocking contacts with girls you chatted with. The game format is more than suitable for flashing out endings, and it won't get in the way of the main story because everything is in the format of short stories.
The main drawback is probably the fast-paced narrative. The events are wrapped up quickly, the backstory almost non-existent. Such an approach might work well for some characters in the story, if the player wants to empty his clip quickly... But for other girls, who have a longer branch of dialogue, you could add more details of the backstory and slow down the course of events a bit.
The last drawback I will probably call "paywalled content". Of course, it is not my place to tell the developer how to present their game, but in my personal opinion, players will give you money anyway if your content is of high quality.
Speaking of which, it was easy for me to find the code without a subscription. Anyway, I still think the game is good. Best wishes for success.
