The art is pleasant, but what really captivates me is the Rune Factory lite like gameplay. It has farming, leveling, monsters, magic, and loot. I'm terrible at the dungeons, but am slowly grinding through them. I'm not sure if the fights are prolonged because of good balancing, or lag though.
The rhythm game is a bit repetitive after a while, perhaps there will be more songs in the future?
In summary, I like the relaxing gameplay and farming, and the charming art. It seems unpolished still. The combat system feels clunky somehow.
