I was extremely impressed with the amount of polish on this game! The visuals have an extremely refined look to them in a lot of ways. The layout is extremely nice-looking, easy to read, and very Marisacore. The characters are styled in a number of fun ways, too! The portraits remind me a lot of the retro anime styles, especially with the eye shape - plus there's a unique take on Sakuya, with the greenish hair and a big vermillion scarf ribbon. The result screen's chibi-like drawings are also extremely expressive.
The music & sounds were also phenomenal thanks to the high energy and personality. The individual songs seem on the short side, but they vary more than enough to make up for it. The sound effects are also a lot of fun; I enjoyed the bouncy selection sounds.
On the writing side, I really liked the way the story's premise was set, as well as all of the ways that Marisa can interact with each of the characters. I remember feeling a small bit of repetition in the writing, especially when the gameplay loop started to flow more - but that may have been merely due to the nature of the game and stat training. Besides, the number of different potential dates (per character!) helped the writing feel unique.
Aside from that, I found the concept and challenge interesting! At a glance - and not having played a raising/dating sim game in recent working memory - this plays well, and it absolutely crushed what it set out to do. Your team did amazing work on this project; congratulations on the top rankings!
