Oil and renewable energy

Some ideas of how the energy can be represented.

The two types of energy that I will use are oil/petrol and renewable energy. 

Real life:

I have chosen these because petrol and oil spills are often main contributors to pollution in the ocean and so choosing this energy comes with consequences. 

I chose renewable energy because it is such a big contributor to NZ's energy and represents positive energy choices, unlike so many other sources. It also relates as there is renewable energy in relation to water.

Within the game:

Renewable energy is slow but clean. You can do the level, but some of the puzzles are not as easy at that speed.

Oil energy is fast and gives heaps of energy but pollutes the water around you. This makes the space darker and harder to see things. If you use this energy the character will start to glow, giving you a little light.
