I went through the official Godot tutorial already, but then I started to make my own game and realized I basically don’t know anything from that tutorial haha.

GDScript is fine, no problem with that. It’s just the whole process of making a proper menu, proper game & enemies, etc. The official tutorial doesn’t really teach enough I think.

I’m mostly interested in 2D games, but 2.5D (think YouTube games) would be quite fun as well.

Any good YouTube tutorials to watch or whatever?

Thanks very much!

For any good tutorials, I usually go to Udemy. Here's one on Godot 2D:

Its paid. But they usually have discount for first time buyer. The price tag I see is CA$24.99 which is very reasonable for 71.5 hours of tutorials videos. That's what I would buy.
