"Demon's World" uses a checkpoint in which a downed single player will start off at the beginning of the checkpoint they managed to reach before dying. Getting hit by enemy fire, colliding against certain stage obstacles, falling off the stage or running against any enemy will result in losing a live and once all lives are lost, the game is over unless the players insert more credits into the arcade machine to continue playing. Although there is an ending, the game loops back to the first stage after completing the last stage as with previous titles from Toaplan, with each one increasing the difficulty.
