Cool concept!
1 issue i had was that the 4th card wasn't playable always. After you receive the 4th card, you can play it, but you can select any other card, put it back, and now the 4th is available.
Took me a little to understand the lying dice concept.
I also would suggest decresing the time of revealing the fake dice. i know you can just roll and skip it, but the sound doesn't stop. It just gets a little repetitive.
Good job nonetheless!
