I got a billion year old rock! Very fun game. Im curious how the age is determined. Is it like an age is assigned and then the graininess and color are both part of making it that age?

Thanks for playing! I'm pretty sure that's the oldest possible rock. Here's how age works:
- Color is a random number between 1 and 9.
- Grain is a random number between 1 and 10.
Color is worth 100 per point while grain is worth 20 per point. That's why you can pretty frequently encounter scenarios where a very grainy rock is older than a somewhat-grainy rock of the next highest color.
...At least, the ranges are supposed to look like that but I couldn't properly dial the color value in before I hit time. That's why there's a light green rock in the tutorial but not in the game :P
