For the most part I really enjoyed playing this. I loved when I really felt I was doing something cool with the chain, but occasionally the physics seemed a tad off (or not what I was imagining at least). The graphics really fit the game well. Sadly, it got more and more buggy as the levels went on with the additional elements which caused some tremendous lag, and sadly the last level froze and did not recover. Still, awesome job, and you should really add a screenshot or cover image.
