This is my favorite game of the jam thus far, and for a few reasons.
1. It uses the theme in a non-superficial way. You have to consider what's on the dice faces as a part of the overall risk/reward tradeoff, which is at the core of the game's design.
2. Simple discrete choices that have the potential to be much more interesting if developed further.
3. It's the ideal vertical slice for a game jam. Just enough gameplay to show the potential for something longer with more depth, but not so much gameplay that it gets mired in complexity and becomes impossible to complete in three days.
Of all the games, I found myself playing this one the longest. I was intrigued by the potential strategies one could employ in picking the dice, passing, choosing which dice to roll and in what order. Although I doubt any game made in three days can have much deep strategy to it, I was presented with something that can certainly be developed into a game with a much richer set of strategic decisions.
This is a solid base to iterate on. If you can add some more states between players, roguelike elements between the rounds, more ways of deckbuilding with the dice themselves, you could have something here.
