Diamond Hoarders

The little hoarders are back, but this time they have discovered diamonds.
In order to get the diamonds they must first bake bread and mine iron.
The more diamonds they get from a mine, the more bread and iron they will need to mine the next one.
Luckily they have found a way to upgrade their buildings and mines using wood, stone and iron.
Help them to upgrade their buildings and mines in order to get all the diamonds.
There are 6 lands to play on including lands with snow and sand.
