I replaced this measly looking tree:
With this:
The new tree is more than 1 tile tall, that means I need to handle the tree obscuring things above it.
Seems easy to make the tree just obscure anything that is a character, but then there might be also monsters taller than 1 tile obscuring the tree… hmmm….
I would definitely need a Y position based obscuring layers, but for now I am just using the simple absolute values.
