I also loved the course, but I agree with sheldonh that it feels like a bit of a letdown that we didn’t take it just a bit further. Two short segments (one on audio and one on exporting) could have polished the game and made the course feel more complete.
There are many aspects we covered in this course that could be considered beginner, but we did it within the scope of an intermediary course. Audio and exporting would have been no different. It’s also important to consider that your most beginner Godot 4 course (the 2D course) does not have an export lesson. So there is definitely a knowledge gap.
Overall though, kudos to Luis and Gamedev.tv for an excellent course that really gives an excellent start into the C# side of Godot.
