The idea is quite original and not something I've seen before in this way!
I played three times and each time I did not understand what I was supposed to be doing though. My guess was to match reaper traits with traits on the top card, but I lost points when I would have expected to gain points.
For example, one person likes gastronomy, but when I click the reaper who likes cheese and wine, that resulted in a failure, even though in my opinion those traits fit together.
The theme is only loosely met in narrative, and even then, it's not quite a strong connection. I like that not everyone made a game about ice and penguins though :D
