Double tapping in context of the NickyD Official Game is when a runner gets two hits in instead of one on the boss's head. It's fairly easy to pull off in a few attempts, but it takes a lot of practice to accurately execute every time. The way attacks are detected in the NickyD Official Game is not based on when the wrench strikes but rather if the head detects its touching the wrench. The head then gains invulnerability for 0.45 seconds, this is visually represented as the head is stunned. The wrench attack takes 0.16 seconds to execute. If the runner can hit the head within the last 0.08 seconds of their attack, the runner can attack again before leaving the heads hitbox effectively getting two hits on the head instead of one. Theoretically the player should be able to get two hits in close enough together that they count as one, but this is very unlikely as they only have 0.13 seconds to execute this and the game engine can vary the time slightly in favor of a smaller window.

Execution: In order to pull off the double tap in the easiest way possible, the runner must rapidly tap the space bar to start attacking. The runner must aim to begin the attack 0.15 seconds at most, before contacting the head and if rapidly tapping the space bar the runner should be able to get two hits in. This will take several attempts to master.
