Silver

Overview
Silver is one of the two currencies (aside from Gold) in Treehouse Tycoon. It is used for building Walkways and Harvesters. You start out with 1 apple harvester and you move on from there.

Obtaining Silver
Silver can be obtained by walking into the room in the centre of your tree that holds the Vault. Clicking on the Vault allows you to spend all the silver your harvesters have generated.

Trivia

 * Silver will do more things in the near future (Furniture, etc.) and it will soon be obtainable by means of Robux.
