I'm starting to give some thought to transition animations in the game. Like everything else in the game, my decision to add a cape to my character is is adding a lot of extra work for me. Luckily, the animation is so small on the screen and everything is moving so fast, that I can probably get away with just a couple of inbetweens for each transition. I just don't know how many transitions I will need. As of now, I'd love to have a couple of frames for when you are swiching from from moving left to right while your flying and running. I'm probably going to also need some for when I'm flying down and and go up. After I get those done, I'll have a better idea of the kind of things I'll need to flesh out the rest.
