About the connection to theme, I consider "Roll of the Dice" a representation of randomness, while the physical form of dice itself doesn’t need to be appeared.
To be more specific, usually when people roll a die they would randomly get a number from 1 to 6. In my game the tiles have 6 colors with different functions. They switch between the 6 colors randomly just like "Roll of the Dice".
Thank you for playing my game!!
