The DS demo of Sonic Colors has hit the north american Nintendo Channel on the Wii, featuring the first act from Tropical Resort.
Upon immediate play it's obvious that this is effectively just Sonic Rush 3, but it has a lot more going for it.
New abilities include mid-air boosting, sliding, wall jumping and Wisp power-ups
The demo is also available on the EU Nintendo Channel, since Halloween.[/p]
My personal opinion of it is that it's better than Sonic 4 to say the least, I want to give it a proper go later than just on an emulator.
