Hi, if you look at the port on the website carefully, you will see that it doesnt come with game files (it is just a wrapper - metadata, patch and android gamemaker runner) and already does exactly what you ask for - instructs people to download files here. Downloads from website dont always translate into installs as some people tend to download whatever latest release is with intention to check later, which they often dont do.
