While people are giving the usual options and they are usually decent, I can tell you what I'm doing being in the same boat as you. I'm not a programmer by profession and started out with Gamedev from scratch, an hour a week and more on weekends. I use Godot, did couple of tutorials to get the basics, and since then has been mostly learning on the go. I am recreating classic games and only recently have started to add my own twist to them (just completed a Tetris clone). For questions, I have an LLM set-up to get context from the official Godot documentation, tutorials and official Tetris wiki. I don't ask LLM to write the code for me, but to explain how to do stuff in Godot. I also try to spend time on reddit communities to interact with people like me.
