Save The Cow

You control a small turret at the bottom of the screen, using your mouse to aim and click to fire at the aliens descending from above. Your main goal is to protect the herd of cows wandering the field; if an alien touches one, it gets abducted. You have a selection of weapons to cycle through, each with different firing rates and strengths, and you need to manually reload your ammo. The pace is steady, with waves of aliens that gradually become more numerous and aggressive. It feels like a tense, focused effort to manage your shots and prioritize targets before your cows are all gone.
