I will gladly say that Fairune Collection and its many components are absolutely spectacular. The aesthetic is perfect, and although the gameplay is really quite simple (walk into enemies to kill them, or die trying), it's still really fun to figure out all of the puzzles and find all the hidden secrets throughout the progress of the game. But my favourite part, by far, has to be the music, because it's freaking *spectacular*. It's one of the reasons I want this series represented in Super Smash Bros. so bad - just imagining "Hope Girl" (F2 final boss theme) remixed into a Smash style makes my heart go nuts.
If I could give this game six stars, I absolutely would.
tl;dr: Buy It, It's Worth It.
