Custom Arcade Mode

KI could have a custom Arcade Mode. People could choose between two options: ‘Limited’ or ‘Infinite’. ‘Limited’ would offer to the player the chance to personally choose which chars would appear in his “tower”, and the player could set the difficulty to each char, individually, or set only one difficulty for all of them. ‘Infinite’ would create an infinite “tower” and you could only choose the difficulty, which will vary from the traditional easy~kyle, with the addition of the difficulty ‘random’, where the opponents will have different difficulties.
