All in all I liked this game. It was not to hard but you still have to be concentrated or you died.
It's not to long, and not to short.
Gameplay worked, and that's important in this kind of game.
Just the road you have to walk if you died was a bit boring.
Either you walked to the boss without doing anything or you have enemies on your way which you don't kill because it doesn't matter if you do. They don't drop enough to waste time killing them.
So after all why 3,5 stars for a ''standard" game?
The score. I really liked the score. :D It fits great to this game.
