I forgot to put in any form of tutorialization, so I guess I'm reuploading this. Left/right arrow keys to move, up arrow to jump (hold to jump a bit higher), down arrow to disable collision with non-metal platforms. Void is a low gravity zone and creeper damages you, but not too much. Oh, I also made some of the jumps easier.

It may be inspiration if you plan making more of platformer maps.
