The game is played by using the left / right arrow keys to change the rotation of the fish, and using the up arrow to move forward. Try to get as many points as possible by eating the smaller fish, while avoiding the angry sharks that will end the game if they touch you. The searhorses will stop your movement, so try to move around them.
Basing off how old styled games were formed, I wanted to make a game that has an unlimited ‘reward’ while having a losing condition. Using knowledge earned from the class, I was able to display and create the game I wanted to.
