Mama Llama has you protecting three llamas from alien attackers by steering a killdroid that destroys enemies as you move over them. If Mama dies, the run ends. Before each round you see a 10×10 grid of waves, with icons and colors showing enemy types and amounts. Using two pointers you shift rows and columns to choose the next wave, while all others keep growing in the background. Limited anti- and retro-genesis devices let you halt or reduce growth, but time is short. Overfilled or completed waves turn into “nogo” fields – and if too many of them end up in your active selection square, your run is over.
