Wing War

These crystals can be obtained by exploring various locations and defeating enemies that transform into crystals. However, there's a catch - certain crystal combinations are necessary to unlock the passage. For example, you need to bring back the crystals in the order of fire, air, water or water, air, fire. If you succeed, a super crystal is formed, allowing you to access the secret passage and try to claim the diamond.

The game takes place within your dragon's limited energy reserves. Be careful not to get hit by enemies, as this will drain your energy and ultimately lead to the game's end.
