I created an offline save on one of my devices and when i logged into my second device same account on steam my save wasn't there like the cloud save doesn't really transfer your offline save online to be picked up by your second device.
UPDATE: As of 0.3.2, Steam Cloud Saves are now available and should sync your Offline Saves!
Hey there! Cloud Saves are not available at this time, but we're working on it as we continue to develop the game as noted here. We'll provide updates as they're available - Steph
Steam Cloud Saves were officially added in 0.3.2, let us know if this solves this feedback item. Cheers! - Steph
