Indeed!

Found to be solvable with moderate lookahead by valerie.

The green line and the ten columns on the right were solvable with line and color logic. Then I used edge logic on the 5 in the bottom row to figure that it couldn't go in columns 1 or 15. Then I tried placing it across columns 2-6 and moving forward with that, but that soon led to a contradiction. Then edge logic said the 5 couldn't go in columns 3-7, 4-8, or 5-9. Then I did the same thing working from right to left, leaving the 5 in columns 6-10. Same thing for the top row. And then the rest solves with line logic.

There's likely a more efficient way to logic it out, but that's what worked for me.

If the circle were orange in color it would be pumpkin pi.
