This was really a nice concept!
I liked how you arranged the whole story and this is quite the premise for a great continuation, maybe with the mechanics getting a little bit more tight and the clues not being told anymore, maybe just with the most difficult clients.
It kinda reminded my of The Sixth Sense or similar narratives where someone has to help the dead find peace.
One thing tho, I got stuck at the third chapter when telling the client about "strawberries". Dunno if it's intended because the story was cut short by time, or if it's a bug :)
