There look like there are some around. I'm just not ready to check into them yet, though. Have you tried the Eclipse editor? That is the nicest editor I've ever used, the way it underlines mistakes and things. The search on it is kind of complicated, though.
As an update to this game. I've got most of the game mechanics worked out now with gravity, collision, and jumping. Although, there is more work to do and animations to add. It's roughed in anyway. Pretty soon I'll be playing around with puzzle ideas. I'm already getting some so I think this is going to be a fun project. From what I've used of it so far, I'm pretty happy with the animation system. It seems to allow quite a bit of control. One complaint I have is with ellipsoidal collision. It doesn't tell you what you collided with or that you collided at all, so I had to set up another collision to do that.
