Awesome! Protip: Don't forget to bring a towel. ^_^
I know I am almost 10 years late but...
I am back to report:
I bought this as well, but I only tried this quite recently (sorry, I have been busy).
I am very delighted that it's not yet another simple DosBox powered DOS game.
The guys at Wyrmkeep did an awesome job of creating a good port that supports a higher resolution than the original DOS version and runs natively on Windows, MacOS and Linux.
