Looks nice, but the gameplay looks like shit. I mean, the dude was just walking in paces, busy talking about the games graphics, when we just wanted to see sonic run around and jump around. He stops, looks at the plants (which aren't nice enough to spend 1 whole minute staring at) and takes a couple of steap around the platform.
Then the falling speed is total slow bs. You jump, and then stay in the air for 5 seconds before you land a metre below. Looks really slow to me.
Nice graphics, but that's not what you show off in a Sonic demo presentation.
