The big twist in Sleep Attack TD is that, in addition to placing down towers to defend your location, you can also quite literally twist the battlegrounds to work in your favour.

So if powerful enemies are approaching from one angle, but your towers that will deal with them most effectively are in another location, you can simply spin the world around and bring the baddies to the area they'll be weakest in.

Neat, eh?

Sleep Attack TD will be available October 23rd on the App Store, and will be priced $2.99 / £1.99. Here's the trailer to keep you going until then.
