Honestly my only problem with the game was I was never (at least with the groupees copy) able to make it outside of the very first room. I havent yet attempted it from a GOG install. But that is a failing on my end im sure as I never could find any support documents online suggesting others had the same trouble.
I dont know if you're still stuck in the beginning room, but I managed to be stuck there forever until I realized that you have to feed to "dying" pup the vegetable in order to begin the story.. Hopefully you're not still stuck, but if you were, hopefully that opens up the game for you.
Also, anyone know how is the soundtrack? I've tried looking around on youtube and google, but all I can find is the music from Pid..
