Bug report: progress lost upon pressing "exit game" on victory sreen at end of second stage. E.g. I had to replay the second stage, because after restarting the game, the game considered my progress as I didn't finish the second stage. :-(
I noticed that if you exit at stage end, and then click in to the level you just finished and hit return to main menu, it marks that stage as complete and unlocks the next area! At least, that worked for me a few times
