Both drive and mediafire would work, use any of them. Download, extract, and play.
When you redownload a new version, all your saves will still be there, no worries.
Okay thank you just in chase, can you somehow actually play it with the app?
I mean you download it and don't delete anything or how does it update without you losing the save?
I mean I started to notice something when I simply tried it out for myself but fully understanding it is probably a bit different.
