Seems to be untested..?? It crashes when going Forward or Backward when at the spiral of the sketchbook. Could you try to do a complete walkthrough of the English versin...
I'll check it this afternoon. Yes, it is tested, but as I said before, I suspect that in the English version it reaches the memory limit and fails. I will have to delete something from the English version or remove a paragraph to adjust my memory. Thank you very much for playing and letting me know, I will respond to you in a few hours ☺
