Hi – we are here to support each other … I think your post is a wonderful start to discuss things that bother all of us.
First my general response:
I share your anxieties. I’m working on a project that I’ve invested over 300,000 words into (so far) and it is in a niche genre, but “in theory” should be attractive to cross-genre readers. I even had a trusted alpha reader express their concerns about this being a niche game.
Yet, I keep working on this and will not let it go, because the need to tell this story grows greater in me each day.
As a niche game, the testing will be ultra-important. You are discovering this importance for your project. As the writer/developer, you are going to have to be very explicit and very focused on how you communicate with your readers/testers.
Concerning your vision… you have to really get into the details with your general readers — yet you are going to have do so in a way that treats them gently.
I’ll continue this in a bit, but for the moment, take your survey results and come up with follow through questions you can ask key readers you have established a bond with…
I have several key readers, I will go back to time and time again to get more focused feedback from… try to establish a bond with a few of your most dedicated readers… don’t ignore everyone else, but use these focused readers as a way to further filter the feedback you start with.
