Re: Major Havoc roller repro

John, you may be right about the player control being the reason for the crystal change.
  It would be just about literally impossible to get past level 16-20 with a Tempest
spinner, it just can't even compete with the number of pulses that a nice roller can
produce. In those upper levels, it is really important to be able to 'jump' complete
hallway lengths.
Using a 'fast' Major Havoc on a Well-Gardner monitor really doesn't look that bad. There
are some misaligned vectors tho, especially when the screen gets really busy or there are
lots of full screen length vectors.
  I will email Owen and see if he remembers anything about this issue.
