a fun game! Normally I feel too slow for such deduction, but since this was a slow text-based game I actually felt comfortable making my own notes and spreadsheeting everyone's locations over time.
As a 'walkthrough' here's my completed spreadsheet (though it's missing one or two key items). Anyone should be able to use it to find any scenes they're missing. However this is FULL GAME spoilers, so don't look at this unless you're desperate, or you like seeing the methodology of others.
