Wow, I really appreciate the donation, thank you so much!
Godot is an awesome engine and really nice if you're starting with game development. Nothing wrong with using spriteheets instead of the shaders, they each have their own use. Glad you like the option between the two.
Let me know if you want some code from the shaders explained at some point, they can be hard to understand.
Glad you enjoy and good luck on your gamedev journey!
