QuantZ comes out of a Canadian game studio known as Gamerizon and this is their lone title currently. QuantZ is self-described as "a unique puzzle action game", but fear not it's far from being an ordinary puzzle game. This game is OpenGL driven and appears quite polished from initial testing. Below is a trailer for Gamerizon's QuantZ.
The Windows version of this game is currently selling for $13 USD, but Gamerizon is currently offering up their current Linux build of QuantZ for free before its officially released. They are offering the (closed-source) Linux version in RPM, Deb, and .tar.gz forms. Gamerizon announced this information on the social bookmarking site Reddit.
