I can help you some tips (im noob gamedev too, i'll really love making games.. it requires time and practice-)
i hope could be helpful for you, for me and for everybody-
- DON'T overthinking yourself to making things, just do it for you.. no fear because you learn something new (thats ok)
- Learning programming first (python or javascript its so helpful-)
- Learning how to use a game engine then (just pick one), im still using godot, you can touching randomly thing or watching a short tutorial on YouTube like how to use godot engine or stuff like that (the monkey see, the monkey do method)
- Playing some games you love it or watching something like draws from other artists or listening some new music to get some inspiration-
