Thanks. Sorry for being all grumpy.
I know it's 15 'cus I used to have a demo of AE before I got the game, and I liked it so much that I spent ages on it, even though it only had the first two tunnels of Necrum Mines (I was about 9 years old). Trying to sap every bit of fun out of it that I could, I became deeply interested in working out how many mudokons could be saved on the demo (it didn't yet have quicksaving, which made those fifteen mudokons agonisingly difficult to reach). Eventually I got the full game and the rest, as they say, is history.
