I.T. Kid

Moolga is a shooting gallery with a dairy theme. The cow fires milk at the sea creatures that surface in front of her, and the mouse aims the shots. Bombs have to be left alone, the storm cloud has to be dodged rather than shot, and the mosquito swarm is its own kind of trouble; the score climbs as long as you keep hitting the right things and stop hitting the wrong ones.

It is a GameSheep game by WitchHut. The difficulty comes from the mix rather than the speed: the screen fills with targets that want opposite treatment, and telling them apart in time is the game.
