gdscript is missing basic features like interfaces (only abstract classes with no multiple inheritance) or custom value types. spawning scenes from code is tricky and not type safe. asset loading and globals are a mess. the engine is built around using a lot of nodes but nodes are expensive, so you need to drop down to confusing low level server apis if you have performance issues.

the worst part is theres no defined build step so `@tool` scripts run both in the editor and at export time. its easy to accidentally crash the editor or mess up your scene with a bad editor script missing one line of code. and as far as i remember its impossible to undo so remember to save often.

godot is still the best option if you want a open source engine for your game but only because bevy is not production ready yet.
