tips
Cool game and heres some tips.
1. If someone that you are fighting gets a power up that you dont like then just keep jumping left and right so that they cant hit you and the power up will eventually wear off.
2. If your enemy has the mine power-up then make them back-track themselves so they get the damage of their own mine.
3. I've found that holding the down arrow and attacking tends to do more damage then if you were to use a normal attack.
