More than a bit in fact. Quite a lot, but "Quite a lot" wouldn't fit in the headline. So here's the deal with Toys Vs Nightmares: It's mechanically heavily inspired by Popcap's wonderful gardening tower defence, Plants Vs Zombies, but instead of using flowers and vegetables to fight off hordes of the undead, you command an army of children's toys against all sorts of nightmarish monsters. It doesn't quite match the level of polish that you get from Popcap's games, but the art is really nice, and it's certainly got better presentation than most free webgames. There's even a simple game to play whilst the main game is loading: I'm only sorry I couldn't include a game for you to play whilst reading this post.
The difficulty seems to be a bit steeper than PvZ, perhaps it's designed with veterans of the games that inspired it in mind. Play it on NewGrounds here.
