I think I grabbed a different version or something, those ghost enemies looked different in the demo I played and the third level didn't look like that, and I think the game page has been changed since I downloaded it. That said, no I haven't played Super Meat Boy or similar games before other than some other people's demos. Maybe if I'd played it with a controller the acceleration and direction changing wouldn't seem so jarring, but I didn't feel like it setting it up. The game is also quite a bit smoother in that video, so maybe my system had to do with it.
