Lol, 60% of devs acually dont plan ahead they tend to fly by the edge of there seat approach to game making. Adding content on a whem then decided against it, restarting, and so on.
Road mapping a game is a clear and easy thing to do. If they simply did that all that's left is simply fill in the work. 80% of why devs make lame excuses as to lack of content each update is due to this. Becuase there still in the fill in the blank process.
Not saying game making is easy, but sitting down with pen and paper is somthing any sixth grader can do.
That aside, I happen to enjoy this game so here is hoping the dev has a clear roadmap set aside.
