That was a small but very good game, which integrates the theme of the jam very well into the gameplay mechanic.
I only have a few things to put out with: the chain sometimes feels a bit too stiff and sometimes the endpoints have rolled somewhere where i didn't want them to be, maybe a point that ties the endpoints tight would have made it better. Second: when the game just started to play a little more with the game mechanics in order to generate more difficult levels, the game was already over. I would have liked to see more levels that deal with your concept even more creatively. But i think it's also a good thing, if i wanted to keep playing. I understand if you haven't had enough time to make more levels. After all we are in a 48 hour game.
Overall i think this is a really amazing game. Great work.
