JUST WATCH.
Thanks @Starship_over_head for the original project. Thanks @Griffpatch for the Geometry Dash character. The rest was all me! Thanks! Basically, Dash, as I'll call him, is going on his regular boring walk when he finds a challenge. The big spikes are dangerous but interesting and Dash wants to jump them all. So he gets the hang of it, and now he's on this big adventure.
