If, like me, you are clumsy and can't beat the dance floor king 100%, this guide is for you.
I have tried to defeat him hundreds of times, but the very end is just impossible to pass, especially on a small laptop keyboard, yet I still want the achievement.
So, I wrote a program in Python that defeats the dance robot for you (a battle of machines, so to speak). I decided to share it with you.

I understand that you don't want to go through the game again just to get the achievement, so I have progressed to the battle with the robot for you, so you don't have to.

Your game save file is located in the root folder of Steam. From there, go to the userdata folder, then there will be a single folder (it should be a number that represents your Steam account ID), then go to the "572890" folder, and then to "remote". There you will find the save file.
If you don't want to lose your current save, copy it to any folder convenient for you.

Now, from the Zip archive you will download (details in section 3), extract the save file (there is only one) and move it to the folder where your save file was located (the folder should be empty and, importantly, the game should be closed at this time).
Now you can start the game and proceed to the next section of my guide.

First, download the archive from this link: https://github.com/LeviBurm/Dance_Pikuniku/

Extract it, go to the output folder, and run the main.exe file.

A small white window with 4 buttons will appear.

This is what we need.

By default, the area where the arrows will be checked is already selected, but this is for computers with a 15.6-inch screen. Therefore, I added the ability to change the capture area. By clicking the button, you can see the cursor coordinates in real-time and then enter the coordinates in the fields. The main thing is that X1 and Y1 are the coordinates of the upper left corner, and X2 and Y2 are the coordinates of the lower right corner.

After that, save. Next, you can check the capture area and see what will be in the area you selected. The cursor will be displayed as a green circle. This area will automatically close after 6 seconds.
Then click start (there will be no message that the program has started working), enter the game, start the battle with the robot, and you can relax while the program does everything for you.

After getting the achievement, you can return to the save folder and restore your old save to avoid losing anything.

This is my first guide, so I would appreciate comments and corrections.
Give it a like, and good luck with your game!
