Fun little experiment to rewrite the algorithm for going uphill with recursion rather than iteration

GoUphill.cs

private void GoUphill(VectorP potentialPos, VectorP response, int y, float potentialDist)
{
    // found non colliding height
    if (response == VectorP.zero)
    {
        // move to this position
        UpdatePosition(potentialPos);
        return;
    }

    // not found? stay where you are mate
    if (y > potentialDist * _verticalMovementTolerance)
    {
        return;
    }

    VectorP newVelocity = velocity;

    // search upwards
    potentialPos.y += 1;
    newVelocity.y = y / Time.deltaTime;
    // need new velocity to fix clipping terrain
    response = GetCollisionResponse(potentialPos, newVelocity.angle);
    GoUphill(potentialPos, response, y + 1, potentialDist);
}
