There are 10 objects:
2 mugs, 2 pillows, a photo, a plant, a calendar, a poster, a blanket, and a set of books.
The books are probably the problem here, as I just found a bug with them-- there are three sets of books, but the next set only shows up if you choose to discard/donate the one previous. If you chose to keep either the purple or green books, there would be a hidden set that isn't accounted for, so the end wouldn't trigger. ^^;;
Gonna fix that now.
Also realizing I should put a "start over" button of some kind on the end text card to make it clearer that it's the end.
Gonna go fix those things now, thank you.
Hopefully for my next game attempt I'll be able to get someone to playtest so it's not just me!
