UPDATE 17 FEB 2020:
Lots of progress today!
Player can collide with objects to collect them. Counter keeps track of quantity.
Objects can also move across the screen instead of just sitting there.
Parallax scrolling works!
Also made a transition to the next level.
I experimented with screen resolutions (default of 1080x1080, 800x600 and 1920x1080). While all of these work, it makes a mess of where objects are placed and the player is a bit slow on 1920x1080. Of course I can change variables to compensate, but I'm thinking it might just be better and simpler to just stick with one screen size. What do you think?
Thanks for reading!
