Bet they still don't allow you to backup your data and move it to another device (one of the big reasons I stopped playing it)
It doesn't let you do it manually, but it lets you login to Facebook (which will then auto-save) and it auto-loads when you login with a new device. There is also an option now to choose which save point - I've only seen this as a screenshot from another player, though. There are "Enable cloud load" and "Cloud load confirm" checkboxes in the second page of the Settings screen.
Though, I only check in every 4 hours to mine gems since I've upgraded everybody to Level 15 and am missing only Nemesis Prime. It's only when they introduce new bots that I start playing it aggressively again.
