The "Gameplay," represented in the phone mechanics (fancy choice selector), is fairly good for a visual novel, but I'd say the gameplay mechanics you find in Sunrider, Danganronpa, or Opus: Echo of Starsong are far more substantial.
I first played the VN to see the other routes that the anime didn't show, so I could enjoy more of a series I loved. But, as time has wore on, I've realized just how insufferable Okabe can be, how tropey the game is, and how silly the premise can seem.
The OST is just absolute bliss, though. It drove me to try to play the piano for the first time, so I could recreate my favorite pieces from the game (admittedly with little result). But, I still listen to them to this day, and it brings me fond memories of my enjoyment of this game.
Overall: 7.5/10 (8) game, 9/10 visual novel.
Gameplay: 5/10
Story/Narrative: 8/10
Graphics/Visuals: 7/10
Audio/Soundtrack: 10/10
