Six Snow Whites and Seven Dwarfs

Six snowwhites and seven dwarfs live in the forest, snowwhites clean mud from dwarfs, while dwarfs work to pay for their lives.

---------------

How to play:

1. Click the coin at the top to enter upgrading mode.

2. Being upgraded, the snow whites clean faster and spend faster. The dwarfs earn faster and get dirty faster. When the lines are blue: earn > spend. When the lines are red, spend > earn.

-----------------

The goal:

Earn 100 units of money. 

But watch out -- When the total money reaches 30, the witch starts to count down. When she goes to 0, she will pick one of the snow whites randomly and send her to 0.

Which is to say, the goal is to earn as fast as you can, so before she counts down to 0, you can earn 100 units of money.

The things I want to try with idle games: 

1. What is the input other than clicking that can maintain the player's focus in a casual but continuous way? It is always short of the snow whites, so sometimes toggling a snow white between two dwarfs can make them both work.

2. Usually, for an idle game, the increment of the requirement for money is more radical than the increment of the ability to earn, which makes up for the growth of the difficulty of the game. However, for this game, I want to try putting the requirement and the earning in the same object and they are balanced while in the same level. (As the dwarf earns and gets dirty, the snow-white clean and spends.) It is the wider and wider gap between each level that consists of the growth of the game.

3. For this special structure, it needs a delicate goal: the total money goes up and down, and the speed of learning is the thing that is gradually accelerating.
