Infoseek lists 2 "Lost caves" entries. One is a boulderdash clone and the other is a text adventure that's listed as MIA. If it's the latter perhaps you should send it in to WoS!
Since he mentions levels, I assume he's talking about the boulderdash clone, rather than the adventure. The Tipshop has maps for the levels along with some pokes.
