Sure, it's not a secret, @brittandjosie. Insufficient funds. That's the short answer. In order to run a contest, you have to reward the players with your upvote or liquid steem/sbd to motivate them to participate. I invested in this few weeks around 100 steem to learn, whether there's a need for such a game or not.
It got more and more popular, indeed, and as @phortun mentioned the quality was growing. So we can say there's a need. :-) Meanwhile, the upvotes on my posts did not change significantly, that indicated that it wouldn't be self-sufficient at the current stage and I need an external source to keep it running.
I couldn't find anybody yet, who would permanently support the project at least partially, so I closed it. I cannot afford to finance it exclusively on my own.
I'm working on my return, I have plans. We'll see. :-)
