The goal is to ensure our scripts are not causing any unnecessary CPU load.

Our game has 145 scripts, but most of them are part of the standard asset package and are not assigned to any game objects. The scripts we want to review are the ones we put in the Assets | Custom Scripts folder. Reviewing that folder reveals that there are only 14 scripts:

BeetleNPC
BeetlePatrol
CameraFollower
CherryControl
CherryManager
CucumberManager
CucumberManManager
HealthManager
PlayerController
PlayerMotor
PointsManager
ThrowCherry
VictoryManager
