you can get outside the stadium with this trick
 
 

Basic technique

so basically you need to fall to one side and jump or slide at the same time, I have these set to c for falling and space for jumping so I can easily press both at the same time. this makes you slide around extra fast. if you do this while facing a wall there’s a chance you’ll pass through it, I haven’t done much testing but it seems to be easiest with one of the barefoot girl characters and while running into the inside of a goal. this can be used to get through pretty much any wall, but it’ll often take multiple attempts so you might need to back up and try again if it doesn’t work the first time.
 
 
 

Other use for the technique

my friends and I were also able to launch ourselves in the air by all moving to one corner with the ball and then doing the glitch-sliding into each other.
 
 
 

Me doing it (spoilers for the only secret in this game)

if you go outside the stadium on the blue side there’s a weird blue box with nothing in it, and if you walk far enough in any direction you’ll eventually reach the edge of the floor hitbox and just fall forever.
 
 
here is the box:
 
 

 
 
here is me upside down after falling off the edge:
