I think you got it! At this point I think you could adjust again slightly to lean towards difficulty or meditation depending on what you want the game to be. I did notice the pace slowed down a lot once I reached gigantic size due to dust not counting for as much and a lack of small enough meteorites, but since that's the endgame, I can understand if that was intentional. An additional idea: since metal stops being useful after upgrading, maybe it could contribute to mass at a similar amount to space dust at that point. Anyway, good update :) I've boosted my rating too if you were wondering haha
