Ahhhh that demo was so much better than the last. Especially considering how fuzzy the PS3 version looked in that old build, plus I think the slight input lag is gone too, so a massive improvement even over the build shown at Eurogamer (although I was told they only had the E3 demo there anyway).
Messed around with it for ages. Both stages are a ton of fun; Modern Sonic feels so much more refined then even in Colours, let alone Unleashed. Very little to complain about from me. The wait for the release of the full game is becoming unbearable!
