Advance through the game by completing all the stages within a level. Once a level is completed, you will continue to the next level. Remember not to fail, because you will have to restart from the beginning (i.e. no checkpoints).
Updates with new levels and features will continuously come every now and then so stay tuned.
If you were to obtain a good score there is fortunately a scoreboard, which means that if you ever wanted to prove how athletic you are to your friends, we got your back.
Note: Rage quit is a guarantee in this game.
