New description:
Zojoin re-release of the game.
If you try to go through the black hole in the Library, the game will
crash from the `op89PUI` script opcode trying to read outside an array.
What black hole, I hear you ask. Well, it's right there on the star map
though you have to select the map to even get a hint about it:
[[Image(star-map.png)]]
And why would you try to go through it? Well, that's actually part of an
elaborate Easter Egg. The instructions I've found for it are:
1. Pick up the two lamps in the first room of the house.
2. Put the lamps on top of each other in the inventory, so that they look
like one.
3. Go to the library.
4. Close the inventory.
5. Examine the black hole.
6. Open the black hole.
7. Close the black hole.
8. Speak to the black hole. (It probably doesn't matter what you say.)
9. Go through the black hole.
(The commands are in the order they appear in the verb window, so that
makes it easier to remember.)
This should take you to this hidden room:
[[Image(easter-egg.png)]]
But you don't have to go through all of that (and in fact I've never tried
the correct steps in ScummVM, because I forgot about the lamps and the
inventory window). Just trying to go through the black hole produces this
backtrace:
