Do you have any artistic or creative background? Can you draw digital art?
I would recommend finding a good game engine, something simple but flexible so you can really make a solid first game, or a tech demo. A good place to start is to just try and imitate another game that you like, and then build on your knowledge from there.
Dont Die is actually my 7th or 8th game, It took me a lot of tries before I was comfortable with the engine and had enough knowledge to make a fully fledged game. But I was always interested in role playing games.
I took a lot of inspiration from Stardew Valley and Rimworld.
1. Find a good game engine, I recommend 001 game creator on steam
2. Make a handful of test games with different mechanics to learn the ropes
3. Once you're comfortable with the program, find inspiration and build on it.
