After entering the kitchen, don't kill mice in a hurry, especially when you meet three, just run away and go to the top corner of the kitchen to get the cockroach killing spirit, add 5 attacks and fight again.

Try to avoid fighting with three mice at the same time, which consumes a lot. After you get three mice, give them to your mother, and then go back to the kitchen to continue the battle upgrade (the mice you get can increase your health). It is best to go to school after level 5. Of course, the higher the level, the better, but it takes a lot of time.

When the number of gold coins reaches a certain level, it is necessary to buy weapons and equipment to enhance combat effectiveness, and also to buy food.

This is the first part of the strategy, which I summarized when I played this game recently. Write for the first time. Not very good. I hope you can understand. Now I have played the role of helping aliens enter the desert, so I can still help the front part.
