Dual Trigger

All incoming enemy planes are protected by two exclusive shields: red and blue. You can only deal effective damage by switching bullets to match the enemy's shield color perfectly. Red shields require red bullets, blue shields require blue bullets - any color mismatch will render your attacks completely ineffective, preventing you from breaking through enemy defenses.
Every time you clear a round, the enemy's health will permanently increase by 20%, making each subsequent cycle more brutal and challenging. Free drag of fighter jets to move, automatic shooting, easy operation. Challenge your limits and fight against the constantly escalating difficulty.
