The Tawashi

Select a stage and difficulty. Use the directional controls to avoid enemy bullets, and shoot down enemies using the attack button. Collect your friends to boost your score, and shoot at present boxes to switch to better weapons every now and then. When you see a flash on the ground, dig up the treasure, and if you get bombarded with enemy shots then use your precisions controls to slowly dodge them. Don't forget to 'pause' if you get tired. It might sound difficult, but you'll get the hang of it as you play.
