The concept itself wasn't the best or most unique, but it was executed so well it more than made up for that.
The game is so simple, but builds on the simple idea of making a dice land on a certain side, allowing the game not to be too short, but it also doesn't last so long as to get boring and tedious.
The character calling you "boss" was also great, and added to the amazing feel and charm of the game.
Great job!
