This is pretty much just following Zep's tutorial from https://sectordub.itch.io/pico-8-fanzine-1, but I learned a lot.

• Figured out how to import a .png as the cart label
• Composed some truly awful BGM (that doesn't loop properly when the tempo increases)
• Every 50 points the ball velocity increases, which at ~300 points causes the ball to clip straight through the paddle. You'd consider this a game-breaking bug if you weren't sick of hearing the music loop already.
