Regarding sprite rotation: this feature has been long time in my to-do list, is something I'd like to implement some day. But as you guess, having it on an environment where you can change rendering attributes at each scanline, keeping good performance, is no easy task at all. In fact, no classic 2D hardware had sprite rotation.
Common approach is to have pre-drawn frames at different angles of rotation, and draw the closest one.
