ProtoPie Tutorial: How to create a parallax scrolling effect in ProtoPie

I just spent 2 days looking for how to do this and couldn't find anything. Amazed that something so simple isn't more well-documented. Thanks for sharing!

Thanks for this! I also spent days looking for how to do vertical parallax scrolling in ProtoPie and this short tutorial is the best thing so far. Have you figured out more scrolling effects and are you able to maybe answer a quick question if/when you have time?

I don't find "Scroll" in the second input, can you tell me why?
