I checked the app to see when/if it mentions this, it looks like in lesson 4 it's kinda mentioned in passing but it's easy not to remember ten lessons later, haha.
I would assume (based on my experience with Python, which GDScript is similar to) that the first example does not work because the order of execution is different. In that example, when "take_damage(amount)" is called, "amount" is first subtracted from "health", then it checks if health is lower than 0, then it checks the level and changes the "amount" after the original "amount" has already been subtracted. I hope that makes sense.
the easiest way to do it is to pack them together in zip files fwiw, so you have the windows exe + pck in one zip and the linux ones in another! that said, downloading them separately kinda fits the game jam lmao
