Just completed the hole demo. It was easy, but the fourth star was hard as hell.
The game is AWESOME. The book feature that gets xp is very nice. I love all the upgrades you can buy, it's so diverse in so many ways. I would purchase it if I had money (no job yet). Graphics are smooth and rich. The music and sound effects were nice too.
The only thing that I didn't liked is that is missing some words, I mean, when I spell them (and I checked if I spelled them correctly) it does not recognize them.
And some quests are for the Full Game only, and appeared in the demo. Yes, I could skip them, but they shouldn't be there.
Other than that, this is such a good game. The potential it has is awesome. I loved the chests were you have to guess the word, and that some monsters demand certain things to be attacked or to deal them double damage. Those little details, for me, makes this an awesome game.
