I have it downloaded it on Android it gives you a link in gmail i believe u access it their click download and once it downloads go to the downlaod tab then click it to install it
It's easy on PC. You pay the $5, download the full PC version (zip file), move the downloaded file wherever you want the game to live, right click on the file and "extract all" to unzip the game files. All of that is the one-time "install" process. Then open the newly extracted game folder and double click on the my femboy roommate.exe file to run the game. Cheers!
