I've played this game three times, it only seems to have saved after the first time I played. The second time was only for 20 minutes or so, so I didn't lose much progress. The third time I made it as far as getting the beta game emailed to me, then when the in-game game crashed, when I went to boot back up in-game, nothing I'd done had saved. Is there a setting I messed up or something?

EDIT: Turns out I did? I had "portable mode" enabled, when I turned it off, things seemed fine. Leaving this up in case anyone bumps into the same thing I did.
