Old-School at it's finest.
Overall I found the game to be quite entertaining. I remember the days of navigating DOS and I still muck about on a Linux machine from time to time. This was quite classical, which made it shine.
The one thing that did annoy me though, was that in the ADV GUI every time you switched from one application to another it popped up that large box announcing the program name, version, etc. Other than that I felt that the game was very smooth, despite being a little bare. Definitely has some great promise for either expansion or a sequel.
