Hmmm, tried a post but I may have deleted it. Here goes again.

Hooray for big maps! I really like the sense of vertigo I get looking down into the abyss as the platforms spiral away. It does seem like there are some strange drop shadow behaviours, where a drop shadow appears on a platform far below the one that is casting the shadow, but you did say you were working quickly.

I'm positive I can find a use for these!

cheers,
