Nice game! Perfectly fits the theme in my opinion. I managed to survive quite long but failed with the robber (presumably didn’t select a 6-sided blue diamond as fake or something like that). It would be nice to see the rules right at display all the time, as it takes valuable seconds to open and consult them (though this might be a design issue, needs testing). The rules presented at the start of the game are a bit confusing - I thought that’s all to the rules (and only noticed the “Rules” button in the bottom-right corner a few customers later).
Anyways, good job!
