Draw the roots of a tree, filling every space on the grid and satisfying the clues on the side. Developed using my fork of Puzzlescript.

Controls: Drag left mouse button to place lines, drag right mouse button to remove them. [Z] to undo, [R] to restart, [Esc] for level select

Rules:

1) Round circles are trees. Roots can branch from this point. You can't add roots here yourself.

2) Place one root (drawn as lines) on each tile. Roots can either be straight or a 90 degree turn. All roots must connect to the tree. (Three- or four-way crossings are not allowed.)

3) All roots must finish with a dead end: they cannot connect to other roots. (Sometimes, roots may already placed.)

4) Rows or columns with a number must contain exactly that amount of 90 degree turns, marked with the red dots. (The tree also counts as a dot.)
