Carton Home Defense lets you defend your home against scary stickmen. You have to hold out until the end of the day.
You have to hold out until the end of the day because they will attack in waves. There are several icons in the bottom left area. These are weapons and ammunition that can help you defend yourself. Don't use everything at once, though. First, click on each moving stickman to try to block an attack. Once you understand there are too many, pick one or more boosts to help. Each boost can only be used once a day, so get more clicks in.
Have fun and good luck!
