I really love the vibe of this game! The emotions corresponding to dice rolls was an interesting mechanic, and I kept the emotion chart open most of the time for deciphering the combinations.
I felt 7 seconds was a bit tight on the time to make the decision, but I can understand why you kept it short to increase the tension of the game. I usually just hit the "All in" button if I was certain of the combination, or the "1/4" button if I was throwing the match due to time running out.
It would be nice for the player to also be able to click the decision buttons first before selecting a die (right now, it seems like you must select a die before selecting a betting amount). I had a tendency to try and hit the decision buttons first, which resulted in some time loss.
Overall, this was fun! Nice job!
