As the core engine takes up so much space, it would be nice if there was a way to compress the Room, Object and Actor content so that it all took up less space (# of tokens mostly).
Current thought is to use "packed" strings for all data except for functions (similar to the method described here).
One restricting factor is that whatever compression method is used, needs to "play nice" with the lua minifier, which drastically reduces the compressed size/character count.
