You are Dough Bro the apprentice baker. All the ingridients used to make the baked goods have been possessed by evil spirits. Cover the ingridients with dough and roll them into the oven. Good luck Bro!
You have to avoid all the enemies and shoot them with dough. When you've hit them with enough dough they will turn into dough balls. When they are dough balls push them using the Z key into the oven.
