Unreality surged through me again. The thing that had grabbed me seconds before I would have made good my escape had looked like something from an old-school horror comic part vampire, part skeleton, part Walking Dead zombie.

Does “make good” mean the same as “make good on”? Is “on” optional here?

Hello, Emsr2d2. You use "would", how does it work? Why not say "it will be wrong?"

Take it as a hypothetical: "If you used it, it would be wrong".
