This game is unique. The location of the player is the same for everyone. So in order to reach the scratch logo (to lvl up), you and the other players must collaborate.
Up, Down, Left, and Right keys move the global character in the respective directions. Space (unless your username happens to be tox123) will stop the game on your end. The game continues globally, however. If by some chance your username *is* tox123, this will reset the player position and the level back to 0. So, don't be rude in the comments.
