A lot of 'relaxing' games actually includes too much elements and made it bothersome rather than relaxing. However, this game isn't one of those bothersome games. It has easy to use controls, nice user interface, relaxing music and gameplay. I didn't get bored after playing for an hour or more. So I'll definitely recommend this game.
P/S: The little storyline in the game is actually nice, I liked it a lot.
