This challenge is A TOUGH ONE, folks.
So there are six different scores you can get in Arcade Audience:
Three normal stages, and three night modes
You must add them all up to 600.
Here's an example: (Max Score for each is 103)
There also needs to be video proof.
Simply send me a video of you opening the game from the Steam Library and pressing the 'High Score' button. I would also like video proof of you getting high scores on every stage, but it is not required.
