I was thinking, what if they added something like Milo% (Really Any gym leader would work but I prefer Milo Because it is short) where your goal is to defeat Milo, or the stated Gym Leader for the category. It would start on the first frame after the cutscene, and end after defeated the specified gym leader. This Doesn't have to be A gym Leader, It could be a trainer but I would prefer if you added the gym leaders (More specifically Milo) instead.
I was thinking if they added a couple categories based off finishing a specific gym leader. For example, Milo%, you would start the timer on the first frame of the end of the cutscene and end when you defeat Milo. Or the stated character. I hope you put this into consideration. Thanks!
