Hello, which operating system are you using?
After extracting the contents of the zip file you would do one of the following depending on your operating system:
- On Windows, open the "Halloween Otome.exe" which has an icon of Kippy.
- On Linux, I believe it's "Halloween Otome.sh".
- On Mac, there should be a Halloween Otome application.
If the corresponding file is not present after download, please check if your antivirus has not deleted or blocked it as a false positive.
