And uses ASCII characters. MegaZeux up'd the ante and allowed you to edit the VGA text glyphs so you could make "sprites."
Back-in-the-day Megazeux and ZZT were like their own dedicated systems, like software console systems. It was really fun to see what people did with incredibly constrained systems.
