The name is just random 😅  
How do you detect if you hit a wall from the bottom?

Maybe if you check if you are going up(negative y) you could make it so you go through walls! Make the negative y a bit bigger else when you walk up the mountain it could trigger!

Or you could make a small line of wall tiles at the bottom and hide them. I find that easier.

(Also I see you used my project! Can’t wait to see what you make! 😁)

Just draw something on a image and then set if pixel at player x:player x  
y:player y-2 is (color) then set y velocity to -1 something like that
