I posted a slower and less complete version in /v/IndieGames a couple of days ago. They liked it.
What I have been concentrating on so far is map generation. There isn't much else to the game yet. You can make a map and hop around on it.
Mouse wheel to scroll in and out
Click and drag to move around the map when scrolled in
FPS and other info displayed at the left side
Hold middle mouse button to center on playable character
Click on tiles adjacent to character to move.
This thing is VERY early in development, but I thought I would get some opinions on it so far.
