How would you make Mario's Backwards Long Jump Cannon?
Personally. I don't have it being ability Mario can actually learn. at least not outside of literally playing Mario 64.
in my Canon. Mario can think he can backwards long jump.
Think.
He only thinks this while under the effect of what I like to call "partying too hard" like at a gala or during a special occasion.
This isn't a literal skill in his skill set, it's just something he thinks he can do after having too much expired juice.
if anyone has an issue with this. I will try and rework it if not scrap the idea.
