I can’t remember why I didn’t pick this up earlier – since I quite like James Kochalka’s work (including his music) – but it’s on sale for a buck right now and so I grabbed it, and I suddenly got addicted to it. It takes Space Invaders, mixed in with Gorf, with more movement on the ground, and the occasional jump (which is the only part I don’t really like). So shoot, shoot, shoot, unlock new weapons, all sorts of variety in enemies and the movement attacks, which all amounts to addictive fun.
