Puzzle Description:

Gravity. Supposed to be Sir Isaac Newton under the apple tree. Had to put a little house on a hill in the background to fill the empty space.

Clever idea, Jay. I like the little house, and how you did the sun. A little more work on the tree, and it could have been solvable without guessing. But nice puzzle anyway.

I hope this doesn't post twice...my internet hiccuped.

Anyway, what I tried to post the first time was that I was able to solve it towards the end by eliminating the possibility that there was a green pixel in row 9, column 21 or 22 (or at least that's what I think it was). I had to look a few steps ahead to do that, but once it was clear, the rest of the tree (and the puzzle) was solvable.

Cute image!

Nice story, tough solve. Needed to guess a far amount toward the end.

I had to guess a bit, too but it was still a great solve! Thanks!

Fun puzzle! Neat picture idea.

This one felt like moderate lookahead to me. Mostly I used edge logic, although at least once I had to employ two way logic. Near the end, I used edge logic to determine if the green pixel in R7C14 is part of the green 2 or green 3. If it is part of the green 2, then the green 3 must be in R9-11C14. This causes a contradiction in Column 22. So R7C14 must be part of the green 3 in column 14.

After that the rest of the solve goes well.
