It's actually a Good one...

At first there are some issues that may piss you off like

1.The main character is .. ugly designed
2.Dialogues and dialogue Scenes are a bit Childish and make the game look "cheap" and not well designed.
3.Graphics are not that good.

On the other hand there are some strong elements in this hack n' slash quest game as

1.It has a nice gameplay although its a bit confused at the start..Battle mode is actually pretty nice and well balanced
2.Game has a great mythological epic story
3.Weapon&character improvement is a plus
4.You can be easily addicted to it, as I did

As a conclusion I'd say It's actually a nice one no matter the negatives...
If you like ancient stories and Hack n' Slash games then you probably gonna enjoy it

That game could be a lot better actually with better dialogues and better cut scenes..I personally am enjoying it much, but there are certainly some issues that may ruin your gaming interest and fun.
