If you download the new version dn install it android usually treats it like an update and keeps all the game's log files and data etc, while giving you the new version
I am absolutely in love with this game! If only I can find a real life kind of Zed... I am picking up a few small typos during the dialog with Doc after the Incident where the Pirates try to take Yoshi back... I can get some screen shots if you like.
