ghosts work, there's just two different versions of ghosts on the same leaderboard, 0.1.5 ghosts don't work on 0.1.6 and vice versa (reverser device)
it's really just to test if uploading/downloading ghosts works, next stable release will have new leaderboards so it won't be a problem

spill issue is that early in dev that i just haven't bothered to save level data yet, not sure what you mean about it giving you a billion gems tho, haven't seen that one
