i would download but for some reason it only shows up as a folder for me
When pressing 'download', you should ideally receive a file named 'endling-win.zip'. You need to extract that using software like 7-Zip or WinRAR, then locate the file named 'endling.exe' in the folder :). Hope that helps.
you can actually just extract files inside of file explorer without using third-party applications. Just sayin'
