Detailed Gameplay

• When you destroy an enemy, a green or yellow medal will appear.
• Taking the green medal will restore your LIFE.
• Your score will increase if you take a yellow medal.
• If you keep defeating enemies within a certain time (120 frames), your combo will increase and medals will be collected automatically when you reach 100 HITs or more.
• Medals are also automatically collected by jumping.
• You are invincible during the laser (after the firing motion is complete).
• Unlike normal STGs, explosions also have hit points.
• If you keep collecting green medals while your LIFE is full, the yellow medal's base points will continue to increase.
• The number of crowns at the bottom of the screen will increase for every 16 green medals you take while your LIFE is full.
• The maximum number of crowns displayed is 30 (480 green medals), but the maximum number of crowns is 4,095 (65,535 green medals).
• When you collide with enemy bullets, your LIFE will be reduced and the number of crowns will be strongly reduced.
• With the exception of some enemies (crabs), yellow medals will appear when enemies are killed by lasers.
• Obtaining a medal also resets the combo duration to 120 frames
