It’s so rare that we get to use the words Wii and demo in the same sentence, and really we shouldn’t be using it now since the demo is for a DS game, but let’s just pretend. The upcoming puzzler Big Bang Mini for the DS now has a demo available via the Wii channel. If you haven’t heard of this clever little puzzle game definitely check it out. There so many games that slip under the radar on the DS the chance to catch a demo of one is great. The full game ships Wednesday if you like the demo.
