Turns out I've not been retaining any save games across Kong (other than those stored on a game server) since the last Flash update - it set my local storage to zero. I had to make a backup, change to unlimited storage, then restore.
Sadly that doesn't fix the fact that replaying even a fraction of this game will be a major pain.
based on gameplay, it barely gets a 2/5. Based on artistic content it might make a 4/5. Oh what to score it.
I think I'll rate it as art, but it'll get a 3/5 for incorporating every cliché in the book.
