UPDATE 16 FEB 2020:
The game now generates a fixed number of objects that appear in random locations. The next major hurdle is going to be the hit detection.
I also played around with the Parallax scrolling. While I got it to work, one issue is that the background covers the other objects that are supposed to be in the foreground. So I got to figure out how to de-conflict the different layers.
Thanks for reading!
