Try to get through the maze without touching the sides. Use the arrow keys. You can go right through the ropes, but that's cheating!
This used the same code base as my previous project, with slight modifications. I downloaded the rope maze from Gordon Johnson at Pixabay, ran it through the free "splitter" tool at https://pinetools.com/split-image, then bulk uploaded the resulting images as costumes. The splitter tool saved my grid with names like row-4-column-2, but with the rows starting from the top down instead of how my original code did it. So I modified the code to reverse the row numbers, and changed the code that assigned the costumes, and away we go! If you remix this, all you have to do is create a giant background image (make sure the width is a multiple of 480, and the height a multiple of 360), run it through the same splitter tool I used, and then do a bulk upload (select upload costume, and then select ALL the split images). The code should handle everything else. Oh, and don't forget to change "world width" and "world height" to the number of images across and down!
