Nice job on your first Jam.
Overall I think it was well done. The only thing I would like to see is visual changes of the leaves well they are on the tree. I had the first leaf and then I was sitting there waiting for them to change, must have had bad luck/timing because every time I clicked a tree they were still the same leaves!
Finally I got all the leaves and set about finding the recipes. I liked that discovery aspect of the game, well done!
