Keep up the good work Robin. I saw in another post (somewhere on here) that you were a little worried about breaking the game with changes. Believe me, I understand that fear with my own stuff, so while I can try to talk you out of having that worry, it's easier said than done.
At the moment you have some number of players in Little Land's playerbase, and the worry would be scaring away those people. If we ignored the current players, even a massive redesign would be a neutral change because while it may no longer draw in player X, it will draw in player Y in his place. When we look back on the current players, any major changes can simply be ignored by players who liked things better the way they used to be. As a single player game we have that choice to enjoy the game based on any version we've previously played.
Lets pretend that a new release just came out, and after downloading it I realize I hate it. I either still have the older version right where I left it, or I'll still have the older version in my download's folder from when I originally grabbed it. I can tell I'm rambling, but in short We-the-players have options and are harder to scare away than you may be worrying about. Feel free to tweak, change, experiment, and flat-out take things in new directions. It's your game and there are going to continue to be players at every step of the way.
