Derivative Clicker

This game takes the concept of buildings buying buildings and expands it to the extreme. It's a seemingly simple design that provides a lasting game experience with a detailed prestige system to enable it to be replayed.

Mechanics
Several mechanics are at play here, most notably the affect of buildings buying buildings. This system takes the first layer of buildings, referred to as "Tier 1", and allows them to be created automatically by the second, "Tier 2". These are in turn created automatically by the third "Tier 3" and so on. The first tier of buildings are the ones that actually affect the game, income per click, income per second, and tick time, where the higher tiers simply increase the number of the lower tiers owned at any one time.
Upgrades can be bought to further improve the impact of these buildings, meaning more per second by a predefined amount. Other upgrades include the automation of clicks and the power of manual clicks.
It should be noted that there are two resources: money and proofs. Proofs can be used to drastically improve income (by a much larger amount than money buildings) but take much longer to afford. Proofs can be considered more of a late-game addition to gameplay.
Prestige is an important aspect of Derivative Clicker, and allows the player to start over with additional boosts to their starting game.
