Yes. The original language was custom and turning into a nightmare. We talked about it over lunch one day and came up with the idea of building a c++ code generator so the level designers could do most of the work with the GUI we made, but the code could be edited by hand as well.

Fun fact, the editor was called DALLAS, which from what I remember stood for "Don't ask Luke for Levels And Scripts". Luke was the only designer who could make things work with the original language.

Personally, I'd love to rewrite it to use wasm.
