Use a Timer because in game timer is NOT accurate

Timing starts as soon as you can hit I to start moving

Timing ends when you defeat the last enemy and the Dancing animation starts aka you loose control of character

For full game runs Pause the Timer at the dancing animation because there is a lot of loading between levels and some PC´s might be way faster then Others

I guess that's all
