About Area 99.9%
This is a puzzle game like VOLFIED or QIX.
The player moves his/her ship and draws lines on the field to gain areas while avoiding enemies and bullets on the square field. The round is completed when the area acquisition rate reaches 75% or more.
On the green line (barrier), you are not attacked by normal enemies or bullets. Impassable blocks are placed on the field, and items can be obtained in rare cases by surrounding the blocks when they appear.
Conditions for losing a life
If your ship touches an enemy or a bullet while drawing a line, you lose one life.
If an enemy touches the line while drawing a line, sparks are generated and follow your ship at high speed. If you touch the spark, you lose one life.
After a certain period of time, a red spark that moves only on the barrier is generated. If your ship touches the spark, you lose one life.
