I'm not even going to go into details. As they say, see you in Mark Brown's video :D
The only thing that I can say is that I'm not sure if leaderboards are a great feature here. It's really hard to lose the game, at least in my experience - for example, I just ended the run with a dice throw cost of 181 and an income of 1495. Getting to the top of the leaderboard becomes not a question of skill, but rather a battle of attrition, which is not usually fun for both top and rising players. If I were you, I'd try achievements for the long-term targets instead - think Cookie Clicker, for example. Leaderboard is definitely a nice touch, but maybe as a supplementary feature, not a main one, especially with 2,5 types of dice dedicated to points.
But that's just me rambling. Love it, straight 5s.
