Why can't I combine certain elements in Doodle God?

In Doodle God, certain elements cannot be combined because they either do not logically interact or they belong to categories that do not have a direct connection. The game is designed to follow a logical progression, so not all elements can be mixed. For example, combining "fire" and "water" will not work because they cancel each other out in real-world logic. Similarly, some elements require you to unlock specific categories or create intermediate elements before they can be combined.

To progress, focus on combining basic elements first, such as earth, fire, water, and air. These often lead to new categories like energy, stone, or steam. Once you unlock new categories, you can experiment with more complex combinations. For example, combining "earth" and "fire" creates "lava," which can then be used to create "stone" or "volcano." If you're stuck, try revisiting earlier combinations to see if they unlock new possibilities.

Another tip is to pay attention to the hints provided by the game. If you're unsure what to combine, the hint system can guide you toward the next logical step. Additionally, some elements are only unlocked after completing specific quests or challenges, so make sure to check your objectives and work toward completing them.

If you're still unable to combine certain elements, it might be because you haven't unlocked the necessary categories or intermediate elements. Keep experimenting with different combinations, and don't be afraid to try less obvious pairings. Sometimes, unexpected combinations can lead to new discoveries and help you progress further in the game.
