This was a nice little game with some cool and sweet stuff.
I liked the graphics. The main menu looked pretty cool, too.
I also liked the music. I found it very fitting and sometimes it would be pleasant and relaxing, other times - fittingly eerie.
That it is made in RPG Maker makes it stand out. What's also distinct about it is the little exploration feature, where Marie can walk around her room and talk about her things. And I liked how the descriptions changed (probably to reflect her state of mind?). But maybe they could also depend on the choices the player makes, what the characters have been doing and talking the day before.
The story was intriguing. And I felt sorry for Marie. And I liked the different endings. And the animation. I thought the part where Marie carried Clovis was pretty sweet. The kiss was pretty sweet, too. :)
