Arrow keys to move do not touch the platforms because initially you could go through them but i edited it so that if you touch the sides you die. you can touch the top though...
Me for the scrolling scripts and someone else (sry forgot his name) for the platform script. (I modified it for this project.) It repeats the same level over and over again so do not keep repeatedly going into the purple portal (As you may recognize from my project Portal Platform!). It is very short but it works pretty well...
