Much like all your other Visual Novels, this is an amazing title that fits into your large connected web of characters, which is always an added plus. The music is very "sweet" if you catch my drift, and it adds a very pleasant feel to the experience.
All of the characters are memorable, and have their own adorable endings for each other (except for the assistant, which I have not found an ending for yet). Plus, the fact that you have connected Treat into the main story gives me hope that these characters could show back up in future games involving treat.
Overall, a very good VN with a large assortment of endings (Haven't found the one after Bad End 2, and the one after Gumdrop's Good Ending), a memorable cast of characters with witty dialogue usually found in your titles, and an adorable story that isn't afraid to get a bit dark at times
Overall another 10/10, nice work <3
