Press the flag, and then use the arrow keys to control the puffer fish. Chase the jellyfish, and every time you get it, you score a point. There is no way to lose, you can play this endlessly. The goal is to get as many points as you can. When you press the flag, the score will automatically reset every time. Reload to reset everything. Have fun!
I followed the first part of a Scratch tutorial, and then added, tweaked, changed, and figured most of it out on my own. Thank you for the great idea and starter code tutorial, Scratch! :)
