The instructions are inside the project. To get to the instructions press the HELP button. I will you give you one piece of advice. Do not press the space button before you are in the game, you can still see the menu screen but half of it will be covered by a wallpaper. I will fix it as soon as possible.(fixed-April 19 2018). You must understand that the game is still a work in progress so there will be some bugs. This game requires the laptop or computer or anything with a keyboard. If your high score did not save, simply go into the project and click the script that saves the high score which is in the backdrop.
Thanks to Demi Levato for the song "give your heart a break" 4/25/2018-High score-200 :)
