this is a challenge i made for myself in which i have to make a platformer using only scratch stuff (meaning i cannot use downloaded images or music, cannot use the line, brush, rectangle, circle, etc.), and the only modifications i can add to those are size changes and color changes (for costumes) and reverse and cut (for music).
the stuff i used is at the final level (only 11(?) levels) use fullscreen for best experience there may or may not be a secret level that you can access through the last level by jumping on the text and through the top part of the wall thing.
