The best mix of Visual Novel and a RPG Tactical game there is. Game takes the best parts from both genere.
On the Visual Novel side you get 50+ hours of reading, great visuals and music, engaging story, and diversified characters.
On the RPG side you get 10+ characters, where each one is a class on it's own, hundreds of skills and spells, which you may change during battle, different equipment for all characters and a unique battle system coming back from Kamidori. On top of that you get simple town management and a couple of crafting systems, that encourage coming back to visited locations to grind for materials.
Different endings, 100+ hours of gampley and a game+ mode if you want to double it. Great package in all aspects.
