I'm making games without any game engines too! I tried Unity but I don't like to move my mouse cursor pretty much, Visual Studio and Visual Code are two frameworks but they are slow loading, I'm using VS just for debugging some glitches, if I can't find them in python idle(not engine or framework).
Yeah, i actually like Godot, this time I took the challenge of doing things my own way, if I where to make something bigger I'd still go for Godot.
If you have struggles with the editors performance I recommend something faster and simpler in features, like Geany or Sublime Text, if you're good with terminals I highly recommend Vim or Neovim (which I use daily) for programming, they have a really steep learning curve but for me they're the best in term of editing efficiency and performance.
