Should I do each module one by one, top down, or should I only touch the ones I find relevant for my needs?
This course works as a collection of tutorial series. The idea is you'll do them in the order that works best for you, and based on your interests.
2D secrets grew really big, much more than planned, and so we're looking to split it into multiple standalone courses when we remake it for Godot 4 (note: you'll get access to all of them as you own the course).
I still have a task logged to add a much better intro to this course. Unfortunately, I constantly have my plate full as of late.
