How do I combine Oil and Fire in Doodle God?

In Doodle God, combining Oil and Fire is a straightforward process that results in the creation of Energy. To achieve this, follow these steps. First, ensure you have both Oil and Fire unlocked in your game. If you don't have these elements yet, you can create Oil by combining Swamp and Energy, and Fire is one of the basic starting elements. Once you have both Oil and Fire, open the game's combination menu. Drag the Oil element and drop it onto the Fire element, or vice versa. This will trigger the combination, and you will unlock the Energy element. Energy is a crucial element in the game, as it is used in many other combinations to create advanced items and progress further. If you are stuck or looking for more combinations, remember to experiment with different pairings, especially with newly unlocked elements, as they often lead to new discoveries.
