Want an alternative to the usual castle windows/walls Layer 3 BG when designing a castle that uses Layer 2? This should work nicely. If you do use this, you'll want to have a Sprite Status Bar of some sort since this takes up all of Layer 3's space. You'll also want to make the vanilla skewers use a different palette, like Palette 2, if you use these with vanilla castle GFX. Otherwise, they won't look very good.
