** Prologue

The more that enemies are knocked over, the more they became invisible.
They are called the invisible enemy.

Against this invisible enemy that had destroyed neighboring countries,
the greatest sword wielder in the country was tasked with thinning them out.
The sword wielder's name was Anna.
She is the daughter of the legendary swordsman Oliver.

Oliver frowned on his daughter being placed with this thinning task, but,
Anna resolved to fight to protect the country, and started out on her journey...

** Dot action

Horizontal scroll/dot 2D action game.

Try to take down their advance positions without bumping into the invisible enemy.
In other words, we should try to reach the base point without destroying enemies as much as possible.
As the enemy are killed, their invisibility increases, and if you kill 20, they will be completely invisible.

If you can escape from the enemy without killing the enemy,
even the leaders in the enemy positions, should not become completely invisible. Theoretically speaking...

Anna: "As a woman, I may have a handicap in swinging swords with my body......I have confidence in my speed."
