The player controls a spider which attempts to eat a single fly on the screen. The fly will flit bout randomly, only staying in one place for a few seconds at a time. The player has a health bar on the left, and gains strength whenever they eat a fly. There are several dangers the spider faces, including cans of bug spray which move towards the player, and drops of water which fall from the sky. If the player is hit by water, they are pushed away from the fly. The player loses a life if their health falls to zero There are also leaves on the screen which move the player closer to the fly. The player has a total of 3 lives, and when all are lost it's game over.
