Yavor - make a copy of this and use it for hoiser hacks. I made collisions, and I'm making gravity rn. You can change the level by going into "draw" sprite and finding the "level" custom block. You can add or remove any "make rectangle" blocks. you use them by putting two opposite corners of a rectangle there, but they have to be in the same plane.
