Overall...I'm not happy with this app.
I don't know what I'm doing wrong. The code and practices presented aren't real code and some things are not defined, presented, nor stated, which for me is just confusing. I can't learn to think how to code if things or logic appear magically.
For example, in the Looping over arrays exercises i was going crazy looking for the error, I hit the solution box, and it turned out that i could write:
for size in rectangle_sizes:
draw_rectangle(size.x, size.y)
jump(size.x,0)
In no point at the code was stated what size was, Is it a variable? Something that Godot just knows because is in one of its libraries or something? The exercises are full of this types of things, places on the code that just use variables or functions that hasn't been defined or I don't know where they come from nor why, and it's hella confusing and frustrating.
