This is a scrolling game engine! Remix this if you don't have a single idea of how to make a scrolling game. I have put some comments on how to edit it to suit your needs. Arrow keys for movement. Don't touch red
Sorry about just being able to walk through the mountain I don't know how to fix that Thanks to @Tralla_kid for the tutorial on how to make it! Check it: https://scratch.mit.edu/projects/597191/
