OMG!!!
I loved it!
Each part of the game, the personality of Periwinkle and Pastille, how their relationship has started and how it has developed until reaching the romantic confession (It has been like a happy punch to my heart<3<3<3<3).
The psychological background, doubts, denial, and relief that came to Periwinkle when he spoke of her feelings with Astragalus (Best girl).
The only thing I was missing was a extra with Pastille's POV of the entire game, and an NSFW patch (But this is because I'm a pervert, and they are too adorable (>///<)).
Coclusion, I love it and I'm going to give it 5 stars.
PS: Please make a sequel<3<3<3<3.
