It looks as though White can no longer win, but the bishop is pinned. Thus, 1. Rxe7+ Kxe7 and mate cannot be prevented anymore. 2. Nd5+ Ke8 3. Nf6+ Ke7 4. Qh7+ Bg7 5. Qxg7+ Kd8 6. Qd7# 1-0.
White is so lost!
1. Rxe7+ Kxe7 (if … Kd8, 2. Qxf8#), 2. Nd5+ Ke8, (if … Kd8, 3. Qxf8+ Kd7, 4. Qe7+ Kc8, 5. Qe8# of if … Kd7, 3. Qd7 leading to mate) 3. Qg6+ Kd7, 4. Qf7+ )leading to mate)

The line: 2… Ke8, 3. Qg6+ Kd7?? Black should rather play Kd8; I can’t find a forced mate.
However, 3.Nf6+ Ke7, 4.Nxg4 fxg4, 5.g6 is winning for white.
