It as called shadowgate
Wow, that really looks a lot like a DM clone ;]
If so wasn't this called Pandora?
The game called Pandora that I remember was set in a space station, although I don't remember any piano players (and I finished it too)... it had a wicked theme tune by Mr Whittaker...
EOB was okay but not really good
What?!? It's the second best of it's kind!!! Heathen!!!
