I've been working a lot on this project without telling anyone ... I have officially reverted to the v2-style polygonal format, but i have made some improvements so i decided to call it v4 of my level layout format.

Yes, it's yet another politically-incorrect photo. I chose this one because, well, 'murica, and because it was 800×560px, which will be the standard for my image sizes.

I will be splitting the world up into regions. (Think about Metroid "rooms" and Mario "levels".) This makes the scrolling background a lot easier to implement, and will make loading sections of the game world easier as well.

As of right now, i have support for polyline collision up and running in the level editor. I will be adding support for region / depth transitions next, i hope. And of course the actual engine needs to be updated with these additional features!
