VanishingPointGame - Broken?

So I started playing the vanishingpointgame, add it behaves very oddly.

Problems notes so far:

  1. if you open a sub puzzle, then close it, it is shown as solved.
  2. after solving the sundial puzzle, I had 20 points, even though it is a 10 point puzzle.
  3. I solved the 50 point hourglass puzzle, and I still had 20 points.
  4. I re-solved the sundial puzzle, now I have 30 points.
  5. Now both the sundial and hourglass puzzle don’t let me play, as makes sense, but still only got 30 points. But it I close the 01.08 puzzle, and reopen it, but let me play (as they are shown as unsolved)

So um, I don’t think I’ll bother playing any more….

Edit: yes I running in FireFox, but it’s all flash, so it should be sweet?
