After watching a KidsCanCode YouTube video, and the release of Godot Engine 3.1, I started learning to make the jump from building 2D platformers to 3D platformers.
I used some crates and coins made by Kenney.nl. I am using the platformer kit, and the cool thing about building 3D games is that I can also use my other skills to 3D print the game assets out.
Game assets in reality. The kid in me is having a great time! I love the future.
