The Dink Network

They wouldn't have to rotate at all. I mean, the original Dink has plenty of examples where there's exact coordinate movement without using the traditional directions. For movement to points in a 30°-60° field you'd have the sprite show its direction 9 frames for example. Circular movement can work the same way. At some point on the circle when the sprite is leaning more towards walking in a different direction change the frames in the same way as I described above.

And even if the latter is too difficult, having circular movement for 1 sequence sprites would still be cool. A circling blade or fireball for example.
