I am in two minds about his game....
Addictive/Repetitive, Boring/Fun,Long/Short game.
It is amazing how many times I try to hit the man only to find the briefcase blocking the way, I mean just curious am i the karate man or is he(business man).
The upgrades are good, though the points systems seems a little steep, after about 15000.
Also would be helpful if instead of actually having to click the man or the hero for the 2 special moves(Energy Blast and Flying Kick) If It could be allocated numbers e.g. 1 = kick, 2 = blast
If you ever decide to make a second one add more moves (with allocated numbers)
Less reactive man(I mean a man who is getting the stuffing knocked out of him should not be able to block that many times...)
Maybe viewable damage e.g. bruises, cuts
and more enemies other than the ninja e.g. samurai?
Still its not half bad....
