Yeah, my girlfriend found that last summer.
We had thought of the name before that, and we when he heard about the flash game we considered changing it... but it seemed like it wasn't a major release and both games are really different. I haven't tried playing it, but it looks a bit like Myst underwater... kinda.
Oh, also, I believe there's a cell phone game called 'Aquaria' that is a Zuma clone underwater. :|
