Thanks for your playing! I spent some time designing the dropping of nuts to achieve a better balance. Regarding those special nuts, the blue smoke nuts will scale down the surrounding nuts, and the orange smoke nuts will scale up. And some gray smoke nuts will eliminate surrounding nuts. Sorry for not having more detailed instructions in the game! My original intention in designing this was to increase the challenge of the game. Thanks again for taking the time to write your review! Hope you have fun in game!
