Development included a huge, well-planned outlay and enormous care to make this a benchmark adventure game. It provided weeks of fun, challenging play. One complication is that several versions of the original game seem to have been released over the last 20 years, and with differences by platform; so when players hunt for hints and tips online, they often find irrelevant, unhelpful or obsolete solutions. The other problem for me was the absence of a single-source guide. I’ve read that others players have them, but I couldn’t find one, so the learning curve was steeper than it needed to be, and I wasted a lot of time hunting for help, sometimes unsuccessfully.
