Aw, It's Twins(tick) Shooter: Waves Demo
Rob Hale's bemusingly frantic Waves has just released a demo. It's a three minute burst of the Crunch Time mode, which you can get from Squid In A Box's main site, here. The full game is out soon, and will be $10 either from Squid (DRM free) or via Steam. But in the meantime, you can finally get your hands on the explody colour confusion.
