Not bad but..
The game it's self is good, despite being too easy but the reason i 'blammed' it was because it's not the complete game. Use this review to help you improve the final game and then re-submit!
The graphics are really good, keep to that style but make it abit more harder and please show people the controls. It took me awhile to finally find out it was the spacebar button to fight back.
Sorry for the blam, but when the keep is finished, then i'll review this game properly. Good luck!
