L and R arro keys move. More killer rocks spawn as the game progresses. I need to work on a lot of stuff. For the future: power ups (get tiny, super speed, phase shift, etc....) different falling things that kill you (Big rocks that block the view of the smaller ones, maybe some exploding rocks that shower little fragments, a bouncing rock, etc...), and even maybe a pause!!!. Anyways... comments,--and more so--suggestions appreciated.
