Another simple free-to-remix template. You control your player with arrow keys through a simple world. The trick with the template is to add long, invisible bars (actually the same color as the sky) that move the world when touched by the player. Some other handy stuff comes here too, such as the player having a built-in option to make it restart the level, as well as another to change it.
The idea is pretty much mine, the only thing that is borrowed is the music, which comes from Minecraft Story Mode. That's all. Edit: I think the glitch involving phasing through walls should be fixed now. Thanks @J2JW for telling me!
