D to go right. A to go left. Space to jump. V to crawl. D and V to crawl and move which is slower than A and D. You need to crawl under the black block and jump over spikes. remember the pencil. THIS IS NOT FINISHED; IT IS WORK IN PROGRESS. Go to the blue line ending thing. Press the flag before starting!
Thanks to @Wolflion_37 for providing the scratch stickman with all the movement which makes this stickman look as good and animated as it can! Check out his game: https://scratch.mait.edu/projects/401956796 I have added code to make sure you can not crouch in the middle of jumpining or jumping while crouching! IT IS NOT A BUG! IT IS INTENTIONAL!
