We wanted leans for turning a long time ago, but the animation setup made this too difficult/time consuming (one of the reasons we're starting fresh with the framework). That and other touches will be done to improve Sonic's animations. Lack of proper/automatic rolling response was not a deliberate design choice. It's incomplete physics. Peelout charge was supposed to be canceled by jump, not down, but Mura switched it for some reason and there wasn't time to change it back. No maps. I've seen a lot of requests for that but it's a heavy handed UI element that defeats the point of exploration (at least in Sonic) and saps the magic and mystery of the world, not to mention it can't account for three dimensional level design. There aren't any map like renders of the demo level either. I've been reading everything in this thread, thanks again for all the feedback.
