Come on guys, you have so many cows! Just let me nab a few! I'm just a cow lover, it's fine!
... Ahem.
This was a fun li'l game! Trying to find unattended cows to steal while avoiding the angry farmers (or grabbing the cows near farmers out of spite) was a good time. After a little while I started toying around to see if I could tractor beam two cows at once, but instead found a bug - if you start to beam up a cow, let it go, and then beam it up again instantly, it glitches out! The cow will either run out of the tractor beam area and go back to normal, only to freak out when you let the button go, or it will float up to your UFO and just hang out there on the side of the ship.
So naturally, I spent a while just messing with the cows by doing that instead.
May also have tried beaming up some farmers, but it seems this alien has no interest in anything but cows. (Relatable, really.)
