How do I combine Metal and Energy in Doodle God?

In Doodle God, combining Metal and Energy is a straightforward process that results in the creation of Electricity. To achieve this, you first need to ensure that both Metal and Energy are unlocked in your game. Metal is typically created by combining Fire and Stone, while Energy is often unlocked by combining Air and Fire. Once you have both Metal and Energy available, simply drag one element onto the other in the game interface. This will combine them to produce Electricity, which is a key element for progressing further in the game, especially in the technology and modern categories. If you haven't unlocked Metal or Energy yet, focus on experimenting with basic elements like Fire, Water, Air, and Earth to discover the necessary components. Remember, the game rewards experimentation, so try combining different elements to see what new items you can create.
