I managed to get 4 people referred to the game (2 returnees, 2 new people, all via Reddit), but after a few weeks, only one of them is still playing semi-regularly. The others managed to get between 40 & 340 points, before going silent.   So I was wondering, how is the situation at your side (you can check it here)? Is there a problem with retention (of both new & veteran players)?
