: The final room is - you guessed it - a puzzle. There are two banks of
: switches and a switch in the center that must be flipped in the right
: sequence, or the ceiling will collapse on you. Actually, it is possible to
: survive even if it does if you move quickly to the room that opens up with
: the mystics in it. If you'd rather not get a headache, you can note that
: the sequence for the switches can be found in Mystic characters on a
: terminal elsewhere in the level. The corresponding characters can be found
: next to each switch in map view. Finish this puzzle and flip the last
: switch, then return to the central building and jump to the bottom and
: it's off to Schmackle.
I managed to find the correct sequence in the terminal, but couldn't get the central building's door open. Either there was a specific bug between this level and the OS X version of Aleph One, or else I simply hit the crucial, concealed switch once too often with the Pfhor staff when fighting the drones and Mystic in the final room. Unfortunately, I had saved over my old game before realising what might have happened, so I now have to replay a whole series of levels to catch up with everyone else...
