Looking to make an open source fighting game demo on godot

Hello, I want to make my own fighting game on godot, however I want to make first a template I can reuse for other projects, and maybe have some code others can use to make their own 2D fighter on godot.

Here’s my github repository with a godot example of what I’m doing.

I need mostly for someone to look over my clumsy code and try to help me improve it.
