The rolling-up-things part worked pretty well. I like the way the items get pulled into the middle of the ball and you can still see them there later.
I definitely understand problems of scale during a jam. Still, you built out a pretty good-sized level. I really wanted to be able to roll up the plane. =)
The ball went nuts when I rolled up the signs at the airport. I assume that was intentional as a sort of end-game, but it was also pretty glitchy, flying around the level and getting stuck in the terrain.
