Amazing job! Very engaging game.
I really liked the tutorial; the rules were explained very clearly and succinctly. Also thought the faces on the emotion chart gave it a lot of personality, and enjoyed the casino theme.
One small suggestion is to add an easy/assist mode that is more forgiving, An audio cue during the last 3 seconds could also be helpful, so we know it's time to make a random guess and hope for the best if we haven't found the answer yet XD
