Sometimes it glitches and so restart and play more! Try not to use up and down arrows that much, it is the reason why it glitches, but here are the instructions. Arrow Keys to move! Try to dodge the spikes on the line. if you get hit by one its game over and press space to restart at the menu click the gear to change sound effects and Music Volume.
Thanks Depicklator for making this great game! It is awesome and rainbow now.
