Difficult but very enjoyable game, you need a lot of training to win this. Fight the great Kind Bowser Koopa to destroy him. You must catch the little Koopa and throw him to the great flying Koopa, in order to hit his head. Continue in this way until you win, and be careful to avoid the traps that he prepares for you.
Use right/left arrows to move; jump with the S key, jump and rotate with the D key and catch the little Koopa by keeping the A key pressed.
