Humble Bundle update?

Greetings. It is updated to Humble Bundle, but it has to be done manually by sending them the package.

When we did that they said that players have to re-install the game to get the new one with could save (Note to anyone reading, this is only on Humble Bundle, not on Google Play or iOS), we don't know why.

So you would have to manually save files "user" and "save" and then transfer them over to the new install folder. I'm not sure if those are saved when you uninstall and then reinstall.
