The graphics are nice, the little ghost is cute. The music blends well in.
But I don't like the commands : the only used mouse button could have been mapped on the keyboard. Even one key for the normal attack and another key for the strong one.
As said by other comments say, the game lacks sound feedback for the attacks and when hit ; I didn't even understand when I got hit.
Honestly, I must add that my daughter looked at the game and went away, disappointed.
The idea is good, maybe more time and tests would have made it better.
