Ya, you're gonna have a hard time coming up with a decent lighting scheme in Graal, so good luck with that. Especially when you consider that giving the player a circular light around them, regardless of terrain around them, is a huge advantage. This is why the light in Terraria is calculated the way it is(with blocks blocking it). In Terraria, being able to see even a few blocks into the surrounding dirt is a huge advantage as it tells the player which direction to dig to continue, whereas light being blocked obscures the surrounding cave systems.
