This is a very simple game, but it has a high degree of completion showing that it was finished as desired by the creators.
　
Although the rule is simple, to trace and delete the continually appearing light particles (neons) with a line, the more neons that are quickly and continuously deleted, the higher the score, but quickly and accurately drawing the line is harder than it looks, so it requires focus that keeps the simple operation from becoming boring.
　
The neons not only come in various colors, but also a variety of forms, such as waves and stars, and as the player advances through the stages, the action begins to change as the neons themselves begin to move and begin to turn off for a time so that you cannot see them, so the player must draw the lines by anticipating the motion of the neons.
At this point, just drawing the lines to delete the neons requires you to think about what dynamics to use, from where to where to drawing the line, and at what speed to delete several neons at once, which begins to add depth to the game.
So when things go as you plan, it is exhilarating and gives you a sense of achievement and makes this simple game very satisfying.
　
In addition, the graphics are also very simple, but the atmosphere of neon glowing in the night is skillfully reproduced, which, together with the background music and sound effects that create the mood of the city at night, creates a good atmosphere.
　
Making neon the subject (world view) increases the attractiveness of this game many fold and the distinctiveness of the game combined with the graphics and sound resulted in producing such a fine title.
　
If this game had simply used some kind of jeweled blocks or a fantasy world setting, which tends to be the case for puzzle games, it probably would not have caught people's attention.
　
Again, the creators did very well at producing the image from the game idea, rules, stage configuration, the world view of neon, and the corresponding graphics and sound—even the name of the title.
　
Although it is a simple game, it has a high degree of completion that catches the eye, and overall, the game can be enjoyed by anyone.

With this game the objective is to reach a high score by using a touch pen to deleting the "neons," spheres of light twinkling in the night sky.
The player must predict the path of the neons, which move in accordance with the rhythmic music to draw a line that aligns with the neons to delete them.
　
The simple rule, the faster and more continuously the neons are deleted, the higher the score, and the distinctive focus it creates, make this a simple game anyone will enjoy.
　
Further, the solid appearance of the visuals, from which all unnecessary decoration has been eliminated, provide a high degree of completion to the image of the neon world view.
