Basically, you have to press the left and right arrow keys to make the bird move. The bird can only move right to left. The red Dino can move any where. With the glider you have to catch the red Dino. I still have to improve but it is okay. (Ignore the fact that I need to improve, it is improved and use the information. One new update the up and down arrows work.)
