Really interesting idea! So many creative usages of a theme this jam, hah!
Graphics is good and i like mechanics. Though, it gets a bit boring at the times when correct numbers just won't show up. Could be good metaphor about gambling, but gets tiresome when you run around tables, doing nothing, for like 5 or 6 rolls.
Maybe no auto-roll, but manual roll with cooldown? So player can utilize every dice they have and reroll only when there is nothing to throw. Was very frustrating when i finally got correct number, but the dice was behind all other dices and i couldn't get in time to throw it.
(And i would really appreciate stand alone build, because web versions of Unity game run like shit)
Other than those minor issues, great job on this game!
