It’s GDScript the Godot specific language, and while I’d say it’s python-like, the GDScript documentation specifically says “GDScript is entirely independent from Python and is not based on it.” hahaha!
Anyway, yeah it’s usable, it has some quirks and the performance isn’t perfect, but as far as a scripting language goes it’s fine.
Worth checking out if you’re thinking of using Godot, or if you already know anything about python syntax stuff.
