Is there any separate apk file links only?
Not anymore, unfortunately. The game is too big for APK, and the engine doesn't really do "install and download" à la "The Sims Mobile".
There is a howto for Android users in the description (find in page -> 1. Download the PC version of the game.), but it's not guaranteed to work, because it relies on third-party software.
It's not really something Runey can fix, unless he starts making outrageous amounts of money, at which point he may or may not be able to talk the developers of Joiplay into making the "install, then download" option a thing.
(Just to be clear, I would not hold my breath.)
