Use the left and right keys to arrow keys to move the background. Press h two see the distance of other players. Press s to submit your distance. (you can only do this once) The background is still a teeny tiny bit glitchy. And the blocks are not moving up and down perfectly. (They may go into the ground if you go too fast) (I would love some help fixing that.) (I don't think it works if you're not signed in.) (if I add the actual platformer longer user names will have an advantage.) sadly does not work if you not signed in.
