Been working on a fighting game project in Godot. Finally got together the basic template/structure for one. These two crash-dummy-like place-holder characters can kick, punch, jump, duck, throw, and perform unique special moves with the classic motion inputs. Plus they each have a life-bar that depletes as they take damage and a winner is declared when someone runs out of HP and is KO'd.
I used a "How to make a platformer" tutorial as a starting point and looked up tutorials on GD-Quest and Kids Can Code for other features. Special-move inputs I figured out on my own, though.
All that's next is to start fleshing it out, create real characters, add more mechanics, refine the gameplay etc. Now is when the fun begins!
