We all only have 24 hours in a day. Don't get me wrong your game is better than most games here (at least in it's promise). But you did decide to release it as it is. So when people have an opinion they express it. Sometimes it's good sometimes it's not. Look I understand the issues of software development. I've done it for 40 years. There are only so many development hours in a day, only so many resources available, and only so many render hours for the images. But in the end an effort has to stand on it's own merits. I don't think the island diversion adds a lot to the game. Other will have different opinions. But that's the way it goes. The advice I can give you is don't take feedback as criticism. It's just input. Your effort shows a lot of promise, but it also has a long way to go. Its the nature of the funding model you're using. But if your subscribers are continuing to grow, you probably shouldn't listen to the volunteer beta testers too much. Also remember I am trying to help your game, I wrote a new walkthrough toward that effort. But listen to all the people asking for help and are confused by the game on this thread. But don't take it personally, even professionally produced and paid for games have walkthroughs and help sites to help the users. I assume this is one of the first games you've ever done and that your learning on the go. So that's the value to you, someone is paying you to learn.
But take the feedback as it's intended as input to help your game and thus you.
