It was a puzzle like Tetris, but the blocks fell into either one huge tray or two smaller trays (versus matches). You would need to make 2x2 cubes to score. There was a scanning laser that went to the right and then reappearing at the left, popping any score combinations. There are also "avatars" and "boss fights" and stuff.
The color scheme in the main menu was yellow, too, and i think it was on steam.
Anyone know it?
