Angelica's zap in level 5 now reflects off the first wall it hits, with sound 70, and stops at the second, as 0x80090554 / 0x8007666c do (docs/levels/level-05.md). Before, it stopped at the first wall.

• 0x8007666c mirrors the direction about the wall's normal: dir - 2 (n . dir) n when the beam moves into the wall. It reflects when the returned angle is 1025 or more, so nearly every hit.
• The port takes the normal from which axis of the step the COL blocks:
  • x blocked: the x direction flips;
  • z blocked: the z direction flips;
  • both: it turns back.
• Checked with play_script in DB05 from the start, zapping in the four headings: each beam turns at the first wall (for example dir (0, 4096) to (0, -4096)) and ends at the next.
