Yes, that's the general idea.

Pretty sure there is no way this game goes 1,000 blocks vertically. I've reached the limits in the sky and in the ground. I'd say it is less than 200...

For whatever reason you can only do splitscreen if you're playing on an HDTV. I don't know that it necessarily has to deal with widescreen, but that is probable. Also, if playing 2-player splitscreen you can choose from horizontal split or vertical split (just like "Portal 2").

Ditto that. GT = JARALDO SVEN

Splitscreen is 2-4 players (assuming you have an HDTV).
