[FEN "8/1nq5/bppp4/1p1k1K1N/1rrp3b/2pp2p1/8/n7 w - - 0 1"]

I found this interesting and unique chess problem online. 

Disclaimer: This is not necessarily a position from a game. It's just a beautiful composition wherein your objective as White is to checkmate the black king. White is moving from bottom to top and Black is moving from top to bottom.

This problem was composed by Hungarian Engineer Ottó Bláthy. 

It's white turn and it's mate in 12 moves. Can you find the winning move continuation for white?
