This edition of the iterative series (each adding new material to the previous game) adds quite a few new rooms and makes previous interactions require more direct input.
However, most of the new rooms are quite sparse, and the new syntax for things isn't always clear (for instance, it took me a while to figure out how to use the (Spoiler - click to show)grabber). Also, it includes exits that are indicated in the status bar but not the text, which I find annoying in most games. Overall, though, I'm still interested in seeing what's next.
