Arrow Keys to move. This is not a game. I was learning scrolling and just wanted to see if I could scroll infinitely in any direction and came up with this. I used it as a starting point for my zombie game http://scratch.mit.edu/projects/17633935/ I've made a more advanced version here http://scratch.mit.edu/projects/20952320/ which causes less lag on more complex games, although this version is probably easier to understand. If you are trying scrolling for the first time, @ErnieParke 's tutorial is an excellent place to start (see credits)
Just a minor edit to make it a good engine for platformers. Credit to @gor-dee and @cobraguy.
