Thanks for the feedback!

Stickman: I'll make some changes before turning it into a spritesheet - the disappearing head sounds like a good idea for the "fastest" backspin frames. If it ever turns into a real game then these are the first pixels drawn for it... we'll see how it pans out. Just spending small amounts of time on this at the moment, and someone else that got in touch on here is coding up the Unity functionality:

(Unity browser player install needed)

EDIT: I updated the spinning frames. Works better now I think.

The animation before the spin is lovely, but I think that the spin itself need either more frames, or some sort of effect to make it look as though the body is rotating, as at the moment it looks as though the head is just swapping left to right. Maybe have a frame where the head disappears.

Is this game in production? It's a neat idea.

I love animation like this.
