A interesting idea and i really do like the look and sound. Gameplaywise the idea is interesting, but being able to set up your own die makes the rolling part almost redundant, as depending on need you switch 4 sides to the wanted action. That way it feels like your "action" has a success chance of 4/6 or nothing. Also the switching sides becomes tedious after a while. If you maybe had pre existing dice which you could choose from to roll, I think the concept would be rounder.
