The game updated and now there is only one chapter?
Hi, so as best I know after the game is updated you lose all your local data, so any progress will be lost (at least in the web browser version). You should still be able to unlock play the 3 levels, but you'll have to play through again from the beginning. Let me know if that doesn't work. I'll see if there is a way to update the game in future that won't do that.
