Oil Pump

The Oil Pump is a place where you can extract Oil. It's located in the middle below the Pyramid in the Underground City.

It has 16 levels (level 0 being the first and 16 last). Each upgrade increases the speed at which you extract Oil and how much you can store.

Tips/Notes:

1. With a drop from a chest, you can hold Oil over the capacity. E.g. at lvl. 6, when you hold 198/200 Oil, open the chest, get 12 Oil, now you can have 210/200 Oil. It allows you to build the Gravity Engine (Lvl.13) which costs 210 Oil.
2. Buying level 16 breaks the game.
