Use the arrow keys to move the cat. It is an advanced scrolling script that... well... you'll see. 'Love it' if you actually do and if you want to use it in one of your projects you will have to put both sprites in your backpack. ALSO the platformer script cannot do slopes. You can use any platformer script as long as the variable names are the same and the last two 'if - else' block's code is there.
All me. I am open to any improvements you suggest.
