I think one big flaw in all of this is the attitude and view of things.
I am pretty sure that everyone understands that Manu is completely buried in work, but the position of "if you can't understand how much work I am doing and that I want to first implement this and this and this before fixing xyz" is exactly what annoys some (e.g. Me and apparently Glaistig and Lulu).
It is nice to have a game that evolves, but you cannot prioritize implementing new stuff to eradicating bugs.
One, you are doing things too fast. Sure it's cool to get new things constantly, but players are like spoiled kids. Give them too many presents too fast, and later on they are bored and very difficult to entertain. You have to hold them at bay, tease them, keep them coming for more.
Two, there is this horrible elitist attitude going on in this community towards new players. I am not pointing at specific people, but I have seen it at various instances. Whenever there were people with problems, complaints or criticism people either reacted with "if you don't like it, leave, we don't want people like you anyway" or "yes, it has been mentioned before, we are working on it".
The first, even though the community really MIGHT be that arrogant to want to weed out people they don't like and not bother with their opinion, this way also loses. I am not saying you should try to appeal to everyone, but if something has been mentioned several times but tons of new players (and probably also but veteran players who simply stopped bothering over time), there has to be something to it and maybe should be worth looking into.
The second, simply needs to be fixed. If it is something that seriously jumps into people's eye at a rate of at least one topic a day then it is something that in the long run will make people wonder what is being accomplished. It's like a toothache that doesn't really bother you enough to go to the dentist, but over time its steady pulsating drives you insane. You can't chew, brush your teeth and everything is just really annoying.
Three, you need people to grow, to attract more people. It's always better to have a well working game with no or few bugs and few features as opposed to a game full of bugs and issues and tons of features. People are happier with the first. In the second, what good are all these features if everyone has something going wrong, something that makes you wonder why it isn't being fixed.
Developing a game doesn't mean you first put in everything at once, and then you see what's wrong. You put in one or two things, see what's wrong, get rid of the bugs and work from there. Besides, once EVERYTHING is implemented, it will be so much more difficult to figure out what bugs cause what problem. And you'll have to go through it one by one again anyway, causing you to lose more time and unnecessary work.
