Found 4 crucial moments (2 blunders, 2 missed opportunitys).
BLUNDER: You hung your Knight. The opponent can simply take it with Bxc6.
Qh3 is a mistake because it allows the immediate loss of a piece. Ne5 is superior because it improves your position and threatens the bishop. The engine line after Ne5 is Ne5 Nxe5 Bxe5 c3, which offers better prospects than losing material.
You had a chance to play Qh5+, a skewer that wins material. After Qh5+, if White responds with Ke1, then Qxb5 wins a bishop for a pawn. This is because after Qxb5, White's best response is cxd4.
You had a chance to seize the initiative with dxe4. This would have opened the position and challenged White's control of the center. White's likely response, Bxe4, would have led to Nf6. This sequence pressures e4 and develops a piece. After Bg2, Black's position is much improved. You had a chance to gain a significant advantage.
e5 hangs material and allows your opponent to force a quick checkmate. Qc3+ is superior because it is the engine's suggestion. After Qc3+ Ke2 Bd4 Qb3, you are still in the game. After Rhd1 Qc3+ Ke2 Qb2+, your position is lost. You were objectively lost here, but this move might have set a practical trap.
