Unfortunately I couldn't get very far in the game due to it crashing. It could also use more of a tutorial besides the included "help" description, to maybe teach the user a simple move command or something.
"terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc"
From what little I am able to play, the concept is super cool. The command-line interface is unique and the puzzle of figuring out what commands work is challenging. Although one could easily cheat by opening up certain included files in a text editor, maybe this is intentional?
