This was made as part of a series on the 12 days of Christmas tune. According to testers (thanks everyone) it should be around 2 stars for difficulty. Hope you enjoy!

Thanks @pseudomonas! Uniqueness deductions are not intended or necessary, but I agree that it would make the puzzle a lot easier.

Love the ruleset! A lot of fun.
There were two points where the assumption that there was one unique tree layout (as opposed to one unique number-grid with ambiguous tree layout) would have led to a much faster solve. Not sure if that was the intended path or not.
Also I spent an embarrassing 30 seconds trying to wipe a pear stem off my monitor.
---------
ETA: reply to @gdc I took for granted that this wasn't the intended path (given that you hadn't specified in the rules "there is precisely one possible tree" and so deliberately didn't take it.)

This was mind bending. It took a while to wrap my head around all the implications of this ruleset, but then it flowed very nicely.
