@boag I did go back to chapter one, and it seems you are in the right. He reloaded back to almost the start, but had spent an hour of time. He's got exactly a year of time to use up, so it might not come into play, but it definitely breaks any ideas about doing long sessions of replays.
I did wonder why he saved so often, but the total playtime limit would seem to be an encouragment to that. Especially since he might not know how long it should take to reach the ending conditions.
