Maybe the implementation is smaller than a typical FORTH?
For instance the FORTH implementation I'm somewhat familiar with (on the KC85 8-bit home computer) was an 8 KByte ROM module, which was packed to the brim - and it wasn't a luxurious FORTH by any means. This Mouse compiler seems to fit into 2 KBytes.
