The game, Gravitron, looks very similar to an old Ludum Dare entry called Graviton:

It's a really cool game concept, even cooler being written in OCaml! :)

Not only is this game a total blast to play, but it's also one of the only games that I think is best played on a trackpad instead of with a mouse.

However if I were the creator of this game, I'd be pretty pissed at the one in the OP. One was obviously inspired by the other.

Convergent evolution :) I made the version version of Gravitron in 2006
