MOONCHILD is a text adventure in virtual machine. Why is it in virtual machine? Because it runs few smaller virtual machines within, that act as full blown LINUX computers within game world that you can get access to. Person who is able to run commands in UNIX shell should be able to beat this game. Although a true hacker should be able to root into master virtual machine hosting the game and inject arbitrary code into running game thus changing course of events in game and achieving the true ending. Mounting game image is cheating.
