This is such an interesting idea for a design challenge!
1. What round did you get to before quitting?
Round 6
2. What was your strategy, if any?
Focus on buying as many cards as possible to buff one die as much as possible
3. What did you most like?
The interaction between the cards and die
4. What was frustrating?
Not being able to carry over coins to the next round, feels like it is missing a bit of a risk reward. Oh should I keep my coins to get over the line or should I spend them on the chance to get a really good card.
5. What did you wish you could do?
I know this is totally against the point of the project but being able to see the dice themselves roll, not having that tactile thing always feels like it takes away from things with dice for me.
