Ok, first of all, thank you for your efforts, game and great time. Your game is really great. You're doing it right. Thanks.
Still there are some issues I want to address. The main one is that you should decide who is your clients: those who is willing to pay or those who doesn't like your game enough to pay 10 dollars? Those who want to pay for the game or those who want to pay to skip the game in order to get unfair advantage? Those who're looking for battle or those who're willing to ruin other's game? Those who want to play long game or those who are bored after a month?
Answering these questions will guide you. Paying options, game design, all the stuff.
When you design permadeath, why is it so necessary? Ok, you really want that... Is it ok for player to start from scratch (or loose mostly all the progress), if this player is willing to play long game? No, it is not.
When you design Nidbanes, what is their purpose? To add some justice and some kind of protection for peaceful players? Why then required stat is stealth? Assuming battle players are already defeated...
When you design Death and saving some exp after it, why are you designing it so gankers will save 50% even if Nidbanes manage to kill them and victims will save only 30%? Is it a game for gankers?
When you design the end of the world, why you position it as a good thing and making a gank-fest of it? What about long-lasting goals and all the creative players?
This list could be extended.
I'm not as creative as you. Your game is awesome, but there are plenty of things to further develop. Your game is awesome, but you have small audience not because of payment scheme. Your game is awesome, but it is easy to ruin that.
Keep it going in proper direction! And again thanks for your hard work.
Btw, me and Atron will be happy to make an interview, if you're interested.
