I was considering getting the Gimp course as a good way to learn pixel art and the Gimp software at once - but apparently they yanked it from the site during the migration or something. Oddly in the side bar when browsing courses one of the filters is Gimp... Oh well. I'm sure there is plenty on YouTube for it.
As such, I'll likely get the "Pixel Art Environments: Design & Animate 2D Environments From Scratch!" as that and the Pixel 2D Character courses are the only ones I don't have which interest me atm (except maybe the Git one, but Git isn't very hard to learn from Youtube tbh).
Now I just need to focus on actually going through the various courses I already have (Yay for HumbleBundles)
