2/3:

Here is the first project I worked on - a little plane game where you press W and S to make the plane avoid some obstacles. It's part of Unity's "Junior Programmer Pathway" and while I recommend it, I do think it's helpful to have some familiarity with coding before trying it as it doesn't explain the coding side of things that deeply (although you can post questions). I also heavily recommend using ChatGpt (preferably 4 instead of 3.5 if you can afford it) alongside it.
