Hi, thank you very much for your comment! The solution you propose is a very good idea as well. Seeing that the asset has received good support, it wouldn't be a bad idea to launch an “extended version” of it applying what you mention.
I am sorry and thank you very much for letting me know, it was something I overlooked when updating the game. The problem is now fixed and the game works as before.
It is not a bug, it happens that the lower half of the tree has collision, while the other half at the top does not. This is to give a depth effect characteristic of top-down games.
You can easily change this by modifying the TileSet. Select the z-index option and change the values that are set in the tree to your preference.
