What do I do after I turn the white mouse green? I can't go to other rooms even after the red rectangles go away.
In the first stage, you need to find all the animals and remember their corresponding numbers. In the second stage, you need to turn these animals green in descending order according to the numbers. But at this time, all the routes you pass through will be closed. If the animals you found turn red, it means that your order is wrong. I think I should design a game end pop-up window to remind you of this.
I updated a picture of the correct route, I hope it can help you understand the game better:
