(Answering the first question, though, the last patch came out on December 25th, 2011, when the game was given wings). LKD left soon thereafter without warning or word to FH staff.
As those above me stated, he came back on his Facebook page and claimed to have no responsibility for FH upon the release of Feral Tales (2D Facebook game that is currently in a publicly playable Beta mode). He still holds the source code that is of critical necessity to properly update FeralHeart, making a proper update for FH impossible at the current time.
