There appears to be a problem with the game's save/restore feature: games will appear to save, but trying to restore these saved games does not work.
Unfortunately we no longer work with the Bunni programmer, so the game is unlikely to ever be updated again and the problem probably won't be fixed. If you have already encountered this problem, we are very sorry that you won't be able to continue your game from where you left off.
For those who wanted to finish the game and don't mind starting over from the beginning, the lead designer says that the game can be completed in roughly 2-3 hours and should work as long as you don't close the browser tab. (I.e., you can take breaks; just don't close the browser tab.)
