EDIT: a request for 15btc was posted here by flazafer, that is still what the reply below is to.

I'm sorry, in business, any gain that is less than the expected gain is a loss. No one made 300% here so everyone lost. 15BTC is a great life lesson, I don't even think I moved that much myself. No idea if anyone is going to actually track the dev of the game down, but ponzis might be acceptable in Russia or China, so there could be no legal recourse. You have been on this forum almost for a year, I'd expect you knew what a ponzi was, and only risked what was disposable to you. Finally, by the look of that address, it could even be a ponzi games wallet.

And now I'm thinking, OMFG, the dev is back seeing if any suckers add to their profit.
