So, the game is really good, it's a good VN:

Story: 8 / 10
Visuals: 9 / 10
Translation: 4 / 10
Gameplay: 8 / 10 (you can't lose, so it's not really a game)
Fetish: 8 / 10 (pretty well diversified)

-1 for the lack of visuals (e.g., a messy room or the stuffed toy you give) and for many small gameplay elements that could be improved
+1 for the ending management system

This makes a total of 7.4 / 10
