SEGA attended this years J-Pop Summit Festival yesterday and brought along playable demos of some of their upcoming games for attendees to get some hands-on time with. Sonic fans were also treated to a presentation of Sonic the Hedgehog 4: Episode 1 on the big screen in the Viz Cinema, where SEGA of America’s Aaron Webber aka RubyEclipse played through Act 1 of Splash Hill Zone in an attempt to beat a time record set at the event. Does he beat it? See for yourself. The demo shown appears to be from a new build, since it has the changes to it RubyEclipse has mentioned up until now at the SEGA Blogs, such as a new running animation, achieving ‘blurry’ feet’ quicker and the ability to run off screen at the end of an Act.

What do you think of this new build? Speak out in the comments.
