Pixel Crusher

This game is a continuation of the nice @PlugWorld's Godot 3 Wave Shooter Tutorial on youtube

I'll made this in Godot 4 and i'm trying to add some new features to learn the game engine.

These new features are:

Skill tree, implemented but not finished; Music Loop dynamics, have some ideas about it; Enemy and spawn variety

If you have any suggestion or question, please tell me in the comments
