It works now, thanks!
One thing I noticed, when the .fnt file is saved for the font I was making (which only has white and #202020), it has the alphaChannel=1 set, which makes the font's shadow semi transparent in Godot, which isn't exactly how I wanted it to look, of course just changing it to alphaChannel=0 is enough to make it look as I expect, but I wanted to leave it here if someone else runs into it
Great tool!
