Can i get answer? Games have two type update function. First from store where it belongs. Second is update downloading in game not in site. I wanted to know before i buy this game. Will my playtime be saved in next update? And where i download new update?

This game is not distributed by official store (Google or Apple). So all updates for phones must be done manually by downloading app installer. And no there is no update option in game itself. And unfortunately itch.io app is not available on smart phones.
At least for android (and PC) devices progress remains saved and it is continued in new version. If for example you go from 0.5.4.2 to 0.6 than your save should work. 0.2.1 is not compatible with newer version, so if you are able to play this version your progres will not be usable in newer versions.
Itch.io remembers your purchases. So you can get to paid content through "My library" at top right. Or at landing page of any product at the top will be notification that you own that product and link do download. And also Itch will notify you when product you purchased has been updated via mail.
That is my general experience with this platform.
