The game may not be in the state you hoped, but it is in a far better and more fun state than many other games and does not have any bugs. Maybe reduce the cost a little if that lets you rationalize not updating it any further. I would just leave the game up and stop reading anything from people wanting it changed. It is a shame for the game to not be played by new people and for you to not be receiving more income from it. The game is great as is. I would be proud of it.
