I think an idea like this is okay but funny at the same time. It reminds me of someone's (not here) sideview battle system idea based off blizz-abs.
But anyway, this idea was brought to me a while ago but I just never got around (or was too lazy) to posting it. Basically, like in Super Mario games, you can jump on enemies and then knock-back (so you can't spam) should send them 1 square back, so that you can attack either a different enemy, or the boss again.
I think if anyone uses this script, it should be recommended for just Mario and sonic games (and maybe disable weapon use)
but nah...
Jump Damage as in Mario.
