I downloaded and installed the .deb file, as I am currently running Ubuntu 9.10. The file installed without any issues using the GDebi Package Manager. My current setup includes a dual-core machine with a GeForce 7600GT video card, running two 19 inch LCDs in TwinView mode at a resolution of 2560 x 1024. This setup is a good test for any game, as games don't always play nice with this resolution, or other running programs. Upon my first run of the program, I had the Hulu Desktop client running in fullscreen mode on my second monitor, and Firefox was fullscreen on the main monitor . I was pleasantly surprised to find that the game started up by maximizing in the main screen, but leaving the Hulu Desktop application running. I've included some screenshots of Quantz and Hulu running fullscreen at the same time below. Quantz is on the left, and Hulu Desktop Client (running the "One Piece" anime) is on the right.

I heartily recommend trying the game. It's a three dimensional puzzle game with intuitive controls and enjoyable play.
