In A Link to the Past there are some levels where the bottom floor on the map can be seen in the background scrolling before you get down there. I was wondering what kind of programming nightmare that might be if even possible at all in Graal. I was thinking it would be easier to just use a screen capture of the lower level but if the actual stage could be seen with baddies moving around, puzzles intact, etc. that might be a really sweet effect. Especially in the case that you've already got really cool implementation for falling off ledges. I was also wondering if it would be possible to implement a height element in Graal so that rather than only X and Y there could actually be a 3D field involving Z movement (could be used for jumping, falling, flying, whatever you might imagine). That way you couldn't attack enemies with projectiles through cliff wall tiles and the like, or if you threw a bomb from a cliff it would fall a little bit further. This is not the same idea as level layering.
