I was originally aiming to complete a mission, hence the ramp shot at 0:11. At 0:36 I've gained a 3x Field Multiplier which boosted all subsequent score gains by 3x. Four shots into Hyperspace were enough to score a million without completing a single mission.

I've been recording multiple tries with OBS for 13 minutes. Then I've used Sony Vegas to cut out the relevant record part and added a timer. Everything else is untouched, even the desktop audio in the background.
