The devs, Dammed specifically, are very bad communicators. In Dammed's other game, when it wasn't updated for a very long time, he disappeared from the thread. Missed multiple release dates too, some by a lot.
That is a bad habit, he seems to be active when things are going good but when things go bad its as if he goes into hiding. He hasn't posted in this thread since July, despite still regularly being on this site.
Alorth is a good renderer and animator, so making the renders and animations shouldn't take that long. He regularly updated his other games. Dammed is a good writer, so it shouldn't take him long to write. So, the only conclusions I have as to why it takes so long is they either don't work on the game a lot (potentially because they both have other games), or they aren't good at working as a team thus making them inefficient.
