besides the controls which were a bit too slippery for me, this is a pretty cool game. i liked the puzzles that made use of the chain physics, though some were a bit too confusing for me to try and solve. i wasn't really sure how i was supposed to go through the part with the green platforms, but somehow you're able to skip that entirely by just jumping over to the other side. even with that though, it's still an impressive game :)
