RANKED BROMON
you fight other people, you gain some kind of currency and level up or smthn. to make it fair (because its really just pressing a button back and forth) maybe we can add abilites, Items or special powers so it would be a bit more strategic.
the ranks could be like copper, silver, gold, diamond etc or just by number
(half of the idea by @thrillseeker) (also this is prolly not going to get added bc it takes a while to code something like this)
