##this won't save much time off your run, but it is cool

Wallrunning is running on the edge of a wall tile, WITHOUT turning. I believe it is only possible on Standard (I've tried to get it to work on Ex Coolmath, but its physics are very different).

It is performed by landing in the sweet spot between colliding with the wall and triggering the wall turn. You can continue to run forward or even jump off it. These are dead easy on Normal, of course, but are definitely still doable in Fast. For Intense, though, I've only been able to do the simpler wallruns so far.

Dangers:

• Overshooting the edge and triggering a wall turn into the void
• You will begin to slide off the edge to one side if you didn't land well enough, so you'll want to err on the side of caution and fall inwards to trigger the wall turn.
• Jumping on a tile too high will make you trigger a 180deg wall turn for the roof.

Levels this can be used on to save wall turns:

• 15 (1s,2t)
• 17 (1g,1t)
• 25 (1s,1t)
• 30 (1r,2t)
• 43 (2r,1t)
• 44 (1r,1t)
• 45 (1s,1t)
• 48 (2r,1t)
  total wallruns: 10
  total saved turns: 10 (est. 5s normal, 2.5s fast, 1.25s intense)
  legend:
  t=turns saved
  r=regular wallrun (just a regular line to run on)
  s=stair wallrun (jumping onto higher wall edges, like in the example video)
  g=gap wallrun (a hole in the wall that you have to jump in and out of quickly)
