Unused Aragog's Lair extended tilemap:
When you compare both Aragog backgrounds you see that this one had more detail in it with less repeatable tiles.
But when all graphics were implemented we went a little bit over the available 1024 tiles limit.
This was including the fullscreen overlay transparent web, Web animations, Aragog and small spider animations
which were all deleted when the bossroom idea was replaced by a cutscene.
