TODO: Add "on touch listener" to demo3

[mithi]

• Add a note in demo3 that the interaction only works on desktop in the <DemoSticky /> component
  https://github.com/mithi/bare-minimum-2d/blob/master/example/src/demo3/demo.js
  Or it might be better to add an "on touch listener"

• Please also remove this weird line space here:
  

  bare-minimum-2d/example/src/demo1/demoProps.js

  Lines 134 to 137 in 07f8e0f

Hey! Thanks for your interest in contributing to this project!

1. First things first, open this on your desktop browser: https://bare-minimum-2d.netlify.app/demo3
   Move your mouse around (hovering) and you will find that the pinwheel will spin.

2. Try to open it on a mobile device like your phone or ipad and you will notice that you won't be able to do the same.

The goal here is to try to make it work both on touch screens and regular screens. Do you think you'll be able to
find out how to do that at make it work?

Please also read the contributing guidelines and the recommended commit style guide! Thank you!
