The issue is that when I start the game (from the .love file, and the main.lua in ZeroBrane Studio), nothing shows and it's just a black screen: http://prntscr.com/klgj4h

Here is an image of what my project is supposed to look like: https://love2d.org/wiki/File:Tutorial-PhysicsBall.jpg

Here's my .love:

Here's the code:

You're running this with LÖVE < 11 with color values that only work in 11. Remove/replace the setColor lines and something will show up.

Or upgrade to 11
