I play on a tablet that usually doesn't come with me. I have considered downloading onto my phone and trying to supplement on the go, BUT I recall ping-ponging my play of a racing game this summer between these two devices, wherein the game progress did not link between the two and I lost significant progress.
The stability of this game worries me as is, so I haven't dared yet. Has anybody else done so successfully for the long term (2 months+) and/or is anybody aware if the game is rated to play safely from multiple devices assuming one has provided facebook logon?
