Anthony Ra – Final Project

The premise of this game is to prevent a crazy, out-of-control lion from getting a head injury and a concussion. Using the character, Ryan, from the messaging app, Kakao Talk, use the spacebar key to control Ryan in the y-axis and have him avoid the sharp sticks. Continuous head injuries can lead to concussions, brain damage, loss of memory and other medical disorders.

Ryan just ate 50 bags of Gushers and is very jittery. It is your job to prevent him from running into those sticks. Enjoy!!
