With the release of GDT on so many platforms, is there any chance you will be making it possible to sync save games across devices? I know you’re about to release a Steam edition, but that will not sync with Win8 App, right?
They are planning to send Steam keys to people that have bought it through Windows 8 store and the Website. So you could just download the Steam version if you want… You can do what you want!
Pssst, The Steam version is not out yet.
It will come. I’m hoping for this too 
I would say syncing across Devices & Platforms & Clients is unlikely but you never know. However Steam does offer this and already supports many platforms and devices.
We should create an cloud saving with registering accounts! We could create one on the forums and you could log on the game to cloud save your data!
