RPS runner

RPS runner is a simple runner type of game. In order to avoid obstacles instead of jumping or ducking, you have to choose the correct item from Rock, Paper, Scissors. Difficulty increases as speed gets faster and the obstacles group closer together as your score increases.

Left arrow key = Rock
Down arrow key = Paper
Right arrow key = Scissors
When game is over, press R to restart

Game is fully functional as of this writing, there needs to be work done but i will continue working and improving the graphics and other stuff.

Any suggestion and comments are welcome. 

Thanks!
