Extra stuff for the game:
Add 3 New Upgrades (Diamond Swipe Chance, Diamond swipe production, Diamond swipe duration.) All upgrades have x^2 (starting at 1^2) cost. (x increases by 1 every upgrade)
Another currency: Blue Cubes (360 Reds)
When all upgrades are golden, Add DIAMOND tier. (diamond tier gives 2x to the upgrade (instead of gold(1.5x)) diamond tier also gives -50% upgrade cost to that upgrade)
