As other say... you might be a jerk. But it is impossible to tell from here.

Putting that aside, it seems that you are in That point. You may consider going to the next level: get some capital, take more risk and pay a good developer. More capital is not necessary finding a VC or that stuff. Think about your friends, your relatives. But, if you go there, you will need to think seriously on your business model and your goals. You will have duties.

Or you should consider your possible exits: are there people interested in buying your project or financing it? Would it be less painful to shut it down fast or to let it die? Could you open it to the community, as others suggest?

But before all that, I think that you should be sure that you absolutely could not find another developer. I mean... why this post in HN and not a "Growing online game seeking for a developer" one?

Hope it helps,

Regards!
