@delshay: as you say, there are other well-known subgames in Apidya: "Heaven & Hell", "Underground", "Pike Stomach" and "Rat Stomach" as detailed on this
Apdiya fansite.
But I don't think "Speed Of Light" could have been seen before as there is a bug in the game (both versions) that makes the game think you've always already played the bonus round on level 4 and so never start it, even if you get to the right entry location.
If you have seen it before I'd be very interested to know where?
There are more details, including screenshots and video footage
here.
