Mechanism test game

Outline: In this test demo, the player can control the avater to jump to different platformers. Also, I set up a plane with random color for the player to watch. No a very fun game,  just watch. 

Controls: "A" and "D" for horizontal move, "SPACE" for jump. Press "R" to retarts the game, and "ECS" for quit the game. 

Things To Do: The player can keep Press "R" to see what happen on the plane, and try to have fun on jump on infinity platformers.
