How to Design Zombies Run

When you first set out to design zombies run, like, did you go into it with an intention? Or did it kind of happen more nebulously? I've always been attracted to unusual kinds of games and games that combine different genres. And so when we came up with the idea for zombies run, part of it came from me just wanting to make running more interesting. It wasn't really out of this kind of belief that games can make everything better.
