, Thanks for taking the time to respond. Yes, well, it looks like I will have to contact their support team for multiple reasons; as I went back in earlier today and played (and played) finally beating that puzzle only to discover yet another complex physically difficult puzzle
[people with physical/coordination limitations may want to choose another game] but also after an unfortunate power outage my save files have once again disappeared and I find I must once again begin the game over.
I am definitely feeling "Hoodwinked". If there is a player out there who could review their successful "save game" process I would feel better that I am not messing things up myself. It appears to have a checkpoint saving system though I'd love to know if there is another method to trigger a quick save between goal checkpoints. Thank you, pd
