You can move the cat player by pressing the right arrow button or the left arrow button, or you can make a two-step jump by pressing the jump button. There are enemy characters in each stage. When hitting an enemy character, the HP gauge of the player in the upper left will decrease. When this gauge reaches 0, the game is over. If you hit an obstacle falling from the ceiling in addition to the enemy character, the HP gauge will decrease. There are other floors that sink when you land, and if you fall, the game is over. If you go to the goal without setting the HP gauge to 0, the game will be cleared.
