Suggestion - Add feature to beam saves across multiple Android devices

[ostrosablin]

I play NetHack on my smartphone on the go and on tablet at home. It just occured to me that ability to transfer your progress from one device and continuing to play where you left on another would be an excellent feature. Right now, I have to play two different games on both devices. Of course, to avoid unintentional save scumming, it must remove save after successful transfer.

The save folder is accessible so you can just copy them over manually (Android/data/com.tbd.NetHack/save). But I'll probably add a link somewhere in the app to make it a little easier.
