Oh man I found this one a bit mind-bending to try and properly control both orbs, but, it is packed with some really cool ideas, not only interactions between the two orbs, but, also with the chain, growing or shrinking it, some really clever stuff in here! Perhaps toning down the sort of physics drift on the orbs would give a bit more control and help the game feel a bit faster and more intuitive in the process. Great job!
