Despite being the third PICO-8 game I've made and obviously the first I'm posting here, this began as my first project. It's also the first project I've ever completed outside of a jam setting. I enjoyed discovering and becoming acquainted with PICO-8's limitations, and I accomplished a lot more than I expected I would when I first started on Cake Quest back in December. If you're interested, you can read about its inception here and about its development here.
I learned a lot, and I hope others can learn from it as well.
EDIT: Modified vertical camera tracking
EDIT 2: Made further adjustments to vertical camera tracking
