Thank you so much! I've been in contact with Jagex. They've give us their legal blessings for our trademark and also license to use their trademark as part of our marketing. But nothing more than that.
We're now working to fix a lot of the issues that were brought up by the awesome testers we got, and then again expanding the game with more features, content and online stuff. I think as a RS enthusiast, you would probably enjoy a lot of the stuff we have in our roadmap :D
First time hearing this. Maybe your application is missing something? Could it be the 200 character limit to the text?
