It's a lot like flappy bird hold space to go up. release to go down. don't touch the edge; if you do, it's game over! don't touch the barriers; if you do, it's game over! you have energy; don't run out! keep your energy stocked up by collecting the blue energy balls. 1.1 update: what's new: the game has now become harder! there's a chance of some random blocks appearing on the stage; avoid them! 1.2 update: what's new: the game is now even harder! the longer you stay alive, the faster you go! 1.3 update: what's new: more noises have been added.
