A simple rogue-like that I completed many years ago for a code-your-own roguelike contest that ended up never taking place. None the less, the simple game is finished. I coded it particularly in Turbo Basic, one of the first compiled Basics for DOS. You can still run the game via a DOSBox, although it's rather slow.

My start on a rogue-like game with a completely randomly-generated world back in 2003. It never really got beyond the overworld generation stage, in part because I lost the source code.

You can download the Alpha where you wander around here although you'll need a DOSBox emulator to run it in this day and age.
The purpose of this game is long, long gone, but I feel it's interesting enough to keep around as a curiosity. Back in the days of Windows 95, the DOS box was less an emulator and more a kind of limited containment device. Most networking interfaces were not exposed to a program running in a DOS box, but curiously enough, NetBIOS was. So this program allowed you to play Tic-tac-toe against someone else running it in a DOS window in those days (2001).
