It's a dog-eat-dog world out there. Or, you know, a baby-eat-grandpa world. At least, that's the world envisioned by Tasty, Tasty Grandpa, an in-development iOS game from Grapple Gun Games.

The setup is simple—you move forward on the treadmill of life, and can eat anyone who's older than you. But as you eat, you grow, and eventually you have to start to watch your back for anyone younger than you are. The goal is to make it to the end of your life and die peacefully without being eaten by any babies. Sounds about right. Who says video games can't be a metaphor for life?
