Lovely little game with CCG and RPG mechanics.
I only played free portion of the game, but if this game is as good as it is in book 1, I recommend it!
Graphics? Eye pleasing!
The best part is visible equipment, bonus points for that!
Music and sounds? Great!
Combat? For me, it's the strongest part of the game.
Every turn you get cards that you use to attack/stun/debuff enemies or heal/buff allies.
You can buff yourself to attack two times in a row.
You get cards by equipping items, like in Card Hunter and you get items from almost every battle, so it's pretty fun.
I suggest setting the difficulty to hard so that it would matter more what are you doing.
Story? I didn't find it very interesting, it's average at best.
I enjoyed the game and I might buy other books in future.
