also another idea: more champions, grey ones have less hp than normal but are a bit faster than normal, the one with a crown above its head will have enemys get one square closer to it (example if a enemy was above or below it would now be in the same lane and would drop a amount of stuff like hearts and coins) killing a yellow one would drop a small battery that would take 5-10 seconds off of a cooldown (based on how long it takes to charge) black ones would explode doing small damage to everything near it (including enemys) white ones that walk through any of the babys and cant be hit by close range attacks (like the thing i think is called red maw also would drop a chest containing some stuff) grey enemys that attract tears to them and drop a bomb on death (a bomb would explode after a while and some enemys might be able to throw it a small distance that hurts anything near it including other enemys) and a special eternal version for bosses and enemys that do whatever you think they should do (new attacks, attack buffs, more hp, armor even?)
