I think you could manage it. A friend of mine did it with zero programming experience.

Also, check out GDQuest if you haven’t.

I’d try going to itch.io and joining a game jam. They will usually give you a theme to work around and it’s a great way to learn stuff. Every time I try to do one I try something new.

Congrats and welcome to the community! Feels great to finish something that works.

Don’t worry that you used a tutorial or assets. Still a good accomplishment
