Hi,
Getting new update differs a little between PC and Android.
For pc you simply download new version, unzip and run, as save files are stored outside the game folder.
For android make sure to install new version on top of the existing - this way you'll update the game and keep save data, if you uninstall the old version your save files will get deleted as well.
As a side note, dev team consists of only 1 man - Moondev himself :)
Have a nice day,
Cheers
