Is this at all connected to my game called ChromoTris? It seems interesting that these games have the same name and both involve falling blocks.

It's hard to avoid similar names with so many games out there. Personally, however, I think that your game has something to do with not many colours, which makes the "chromo" somewhat inappropriate. I would have rather called your game "Duotris".
