LucasChess will analyze games and give ratings based on how closely you match the engine. It even shows overall, mid game, and end game. I'd plug your game into that. It will also show a bunch of other statistics, too, about piece mobility, domination, etc.

Haha, vinegar dissolves Cryptex's right? Better not spill any .
