-----Welcome to Mountain Generator!----- First, enable Turbo Mode by clicking the green flag while pressing shift. Then press the "Generate New" button. Keep pressing it until you get a mountainous scene that you like. Press H to hide the button so that you can get a picture of your scene. Press H again to bring the button back. You can get 5 different types of mountains: sand dune, snowy, rocky, spring forest, or fall forest.
Made entirely with pen. You can take a picture of your mountains if you want and use it for other projects. No credit necessary. It works well on TurboWarp with 250 fps, high quality pen enabled! Thanks to @WittBitt for testing.
