Added Sprint mode, using existing teleporter exits as checkpoints. Playing it in Challenge is still ~cool~, though.

It's about time I did an update!

• Increased angular drag values across the board--should be harder to spin out of control in zero-G areas now
  
• Made music changes less weird (the bugs got fixed!)
  
• Made it more obvious that alternate paths outside hyperspace entrance go nowhere
  
• Made transition to main hyperspace less sudden (now it doesn't look like you have to aim for a tiny teleporter)
  
• Placed more tracks in end area as safety nets if you fling out of last building at an odd angle
  
• Added difficulty rating!
