If you were attempting to find casual gaming gold, you might well think about trying to create a game at the midpoint of Plants Vs. Zombies and Diner Dash. That’s pretty much what Black Market Games (created by a group formerly from Dark Water Games, they of Dogfighter) have done, with Dead Hungry Diner. A game in which two canny orphan twins realise the best way to thwart the zombie apocalypse is to feed them. In a restaurant. In a graveyard. You can check out the first eleven levels to see if that works for you via the demo.
