Draw edges between triangles around dots.
Ivy Slyly is Zachary Talis' submission to One Day One Puzl Week 39.
You can find an earlier Ivy Slyly in Gumdrops, a custom Witness-style puzzle sequence.
Special thanks to Deusovi, Kaia, and Katelyn for their rule-wording contributions!
On a square grid, draw edge paths (ivy) between triangles (roots).
Distinct ivy paths may not branch or intersect, but any root can be an endpoint for multiple ivy lines.
Each root points in a direction. Ivy must never grow opposite its original root's direction.

All dots on the grid must be satisfied.
A dot points in the average direction of occupied edges of the cell.
If no edges contain ivy, the dot points in the average direction of occupied corners of the cell.
At least one corner of each dotted cell must contain ivy.

Dots must all have unique borders.
Ivy must not emerge in the same direction from two roots pointed in the same direction.
