m&m 2-player rpg idea

I'm working, real casual-like, on a short story game for 2 people that uses M&Ms as the randomizer.

The idea is that you're out with your friend, you want to play a game, but you have no game supplies.

Walk into a convenience store, buy two individual bags of peanut M&Ms, and you're ready to play.

There are 6 colors or M&Ms and there are numbers concerning their relative frequency in each bag. There are typically 20-24 M&Ms in a bag. At those moments of randomization, you reach in the bag for an M&M and follow the color.

There'll be special rules for mutant M&Ms, like those ones with two peanuts under the same candy coating.

Other possible affordances are the size of the M&Ms (especially useful if there is an opposed event of some kind), the stamping of the white "m" on the candy, the roundness of the candy, or definite cracks in the coating.

I know, you want to play right now.
