I have to say, while this is nowhere near the level of detail the original game certainly deserves in the end in terms of graphical upgrades and new revamped dungeons and whatnot, this hits it on the head of very strongly iterating on the original engine. I can't wait for the source code to be launched (once the initial wave of bug fixes squeeze through). I especially love the new menu setup with it just pausing the current game and then being able to reload it. It will be very enlightening to see how that tinkers under the hood.
For what I heard was about two months of work, this is an amazing job well done.
