This is one of the only games that has ever brought me to ugly tears. To The Moon and Finding Paradise (similar, more well-known games in the genre) had a couple tears sneaking out of my eyes, but nothing can come close to the emotions that Rakuen brought up for me.
A huge highlight of the game is the soundtrack. Laura is an amazing composer, and each piece of music in the game is tied to the storyline like I've never seen before.
