you have to unzip the .7z file. Unfortunately itch.io didn't allow me to upload the folders only it must be zipped. Probably right click the file and select unzip?
Ah. I apologize. 7-Zip is an open source file compressor like winrar. Have been using it for years that I forgot most people probably don't use it. My bad. I guess installing 7-Zip will allow you to unzip.
