Cute little game! Was this made with pico-8?
The art style is simple yet easy to interpret. I like how you used simple animations to identify things of importance, like humans and dogs. I also like the premise of abducting humans while the game has a lighthearted feel to it, like where the first guy I abducted seemed to come willingly.
On the earth map I couldn't figure out where to land, so I just randomly moved to different spots of land until something happened. I'd suggest making this part a bit more clear.
I died very quick when I decided to check out one of the dogs in a building. It would be cool to have a checkpoint system to get back to the game quick after death. Also more of a warning for instant death would be good if you feel that fits in the game.
Great job!
