As I stated in our full review, Waves is absolutely fantastic. It's a gorgeous, sumptuous shooter that provides the addictive draw of games like Geometry Wars with deep new slow motion and scoring mechanics. You can get a discount by ordering directly from the developer himself... as well as the warm satisfaction of donating all of the proceeds to Rob Hale rather than letting the retailers get their cut. You'll get a Steam code, so it's the best of all possible worlds!
Plus, it's Hale's 30th birthday. Think of this as a party bag.
