A tour showing what gameplay is like on a pair of red alien planets about 10 million light years away from earth+a break section with some more comprehensible (but just as good) gameplay with some amazing structuring that's been a big inspiration to me. There's clearly still some remnants of the first planet's architecture (both start with similar slope-filled ship gameplay), but generally they're quite different. I would highly recommend visiting the Thycket system if you have the opportunity, just remember to bring enough practice checkpoints.
