The high scoring community should also have a place in the leaderboards, even if it is under category extensions.

Even if some moderators believe it would turn into who plays the game the longest and it's "uncompetitive", players are still running it. So it should get some recognition.

If I were to suggest some category rules it would be time ends one briefcase fadeout, no Vellon Skip.

isn't this like DoN mode above 800k?

800k is really low, it's barely 15 rounds played. The current max score records sits at 30.
