At first I wasn’t sure if we were looking at the inside of the balloon, or the outside.
I finally decided it had to be the outside.
Yeah, the outside… I think.
Oh, I made a rotating pieces puzzle just to give you a bit of an extra challenge.
(left-click to pick up a piece, right-click to rotate it, left click to put it down.)
Enjoy!
