The Crystallographer

You are the crystallographer. You make a living growing and  selling crystals in your undeground crystalarium. Plant crystals and wait for them to grow. Once a crystal is fully grown you can harvest it for money, or break it to grow more crystals.

Different crystal colors all have different growth rates, sell value, and spread chance. Strategize the best way to sell as many crystals as you can before time runs out!
