I agree there aren't very many. I can think of PuzzleScript, Unreal Blueprints, and Machinations (mentioned elsewhere in this thread). Perhaps this dearth is why Blueprints got so popular?

Honorable mentions might go to PICO-8's flavor of Lua (C-like but clearly designed to create a specific type of game and have a specific developer experience) and Excel (used for developing & balancing game mechanics, but usually replaced in the final product).
