"“We didn’t want to fall into the Kickstarter trap of adding more stuff to the game, which adds risk and bloats it,” he says. “We weren’t thinking about it from a business perspective, it was as fans of Kickstarter itself. We don’t like it when other people over-promise. If you take our stretch goal to add an orchestral score – that doesn’t add risk to the project. Any more that we add will just be giving specific features to the fans, we don’t want to make our lives worse by adding stuff that may well mean we miss our release date. We’re going to try to do the opposite of what a lot of people have done on Kickstarter – if a stretch-goal feature is vital to the game, then why wasn’t it in there to begin with? It’s important to learn from the lessons of others. We’ve had a lot of first-time Kickstarter backers, it’s our responsibility to show off the platform.”"
