The instructions are in the project. Try to do what the instructions tell you to do so you can score more points. Try not to press the space bar too often or too many times (even if your space bar on your computer doesn't work); the project WILL glitch for sure. Also, be sure to click the green flag 2 times!! I have made a high score variable now.
Thanks Ellesong! I edited some sprites and tried enhancing the game too.
