Hello, I am building a continuous sidescroller game using Phaser. the game has parallex scrolling background, i have added the background as tilesprite and given it autoscroll. i am spawning the ledges on which the player runs as the game progress. my problem is that the game is a bit jerky in nature, it sometimes lags for a sec or two what can i do to resolve this? any suggestions are welcomed http://gamegurus.com/demos/RunningMan/ , here is the latest build of the game. Thanks
