Making progress!
I've decided to make my maze a timed escape game.
You're lost in space, and there is no sign of the rest of the crew. The power is out, so you have to rely on manual locks and a flashlight to escape. However, this craft is now very dangerous, as it is malfunctioning. You know you have to escape the craft before you are out of air... and before you meet whatever you hear lurking in the hallways.

I just figured out what the theme was, but I also wanted to actually avoid showing this while I was working on the early parts of the tut, hoping people wouldn't copycat me, I'm not making a tutorial like that. I actually want to show beginners everything they need, and some, to finally publish their first Godot game, from how to use variables, to where to get assets, to asset licenses, to game mechanics and art, and of course, the final production. It's a massive page right now, but I am confident that I will finally be able to end this games tut soon.
I have dabbled in Godot before, but I will have also actually finished a Godot game for the first time. =)
As for those taking the course, if you have been doing Godot for a while and just want to know more, and the very beginners, I was curious on what you thought of adding AI enemies and enemy shooting? These features will be very basic as they are your first enemies, but they might give your game(s) just enough to keep your players on their toes.
Also, I am giving all credit to the method I would like to use for state machines to @fire7side , as I read a post from him about basic state machines. If you see this, @fire7side , your idea was brilliant and would love to add it in so beginners can set up their first bad guys!
The tut is casual, I get nothing from it. I am only doing this to help beginners. If you are a beginner looking to learn Godot, check out my link above.
