It took me a long time to teach my character how to swim . I think we're just about there, although some of the animation blends still need a bit of smoothing (there is something that feels a intermittently glitchy about the animation blends in spriter, but only sometimes....).

I am considering making this the last game demo so I can focus on making the rest of the game without giving all of my secrets away. Alpha and beta testers are always welcome, however . You know who you are!
