do you have downloaded WinRAR to extract the zip file?
no.... how do I download it???
it's a pretty well-known "software" so you can find it easily on the Internet; it will allow you to extract all the files from the .zip
when you've downloaded it, right click on the to_the_edge_the_sky.zip file, then select "extract here", then open the BTS-all file, then open the .exe file
I downloaded it but, the game isn't working
