Some people have nightmares about taking out their zombie wife with a sniper rifle. Me? I'm spinning through 3D space at high speed fretting about getting shapes to fit through narrow gaps. Horses for courses.
Even with some minor flaws like the little VARIETY regarding the levels and the number of Keydrons, ThruSpace becomes compelling and worth 800 Wii Points for your purchase, turning itself in a different puzzle game, but unambitious.
