Tap the right side of the screen and slide your finger left or right to move the player, and tap and slide the left side to move the viewpoint. There is a huge monster on the stage, shoot objects at this monster, and if you hit it, the score in the upper right will increase. If the object falls to the ground without hitting the monster, the life in the upper left will decrease. When the number of lives reaches 0, the game is over. Compete how much you can raise the score before the game is over.
