Honestly Gree, having 20 little characters walking around in circles right next to each other makes this quest seriously not fun. Do you guys even play your own game? Games are supposed to be fun. This is torture. It's even bad on an iPad, much less a phone.
Quit having these whack-a-mole fests on the docks and at least move them to a map where the 25 bots can spread out a little in future events. Your game will suck less that way.
