Hello! I think that something that would add to the game is if items in your inventory showed how they impacted the score of the dice roll, like how jokers show their effects in Balatro. It would slow down the rolling aspect notably but I think thats a good thing. Obviously there isn't much to do during this section but it would make it more interesting.
Another idea is adding a visual dice roll, rather than just showing a number. I imagine that would be pretty tricky to do, but I think it would also spice up the rolling section by giving more visuals.
In a similar vein to the last idea, I think perhaps you could add custom dice. Whether that's changing the colors of the visual die (if you choose to add that). Or just adding dice with different odds (kind of like the Mario Party ally dice system)
No pressure to include any of these! I look forward to following the development further.
