I think something strange happened the first time I downloaded it, I didn't have the jumping with sword sprite, but I re-downloaded it and it was there. Maybe I accidentally deleted it the first time.
This is amazing, I was wondering if it would be possible to make a jump set where they are holding the sword, if not that's fine because this is already so amazing!
I'm not using it for commercial, but I want to credit you anyway, should I use the name JumpButton?
