Good stuff. Good call drawing a line too - the fact that you've effectively developed the game since the DOS days is amazing enough in its own right!
New major version - same great game
Now is the time to re-visit this game if you were maybe put off from playing the game in the past due to some glitch, or just want to re-play through. It's the same old game, but with a rehaul of the engine, with many performance, visual and control tweaks. This should be a good place to draw a line and seal this game off so I can focus on other projects.
