This is like a whole new style of game. I can't think of anything that it is like. I think you've got a great starting idea here. You need to do something to jazz it up, though. It gets boring after a short while of play. Maybe put in different kinds of objects, worth different points. One way or the other, you definitely need to increase the speed, make it faster paced. Maybe add levels, too, where things change after you collect so many rings. Also, there was some number off to the left that I had no idea what it represented... I like the dual controls, using both mouse and keyboard at the same time. I like the jumping from object to object, and the positioning rings before you select the next object. The sound loop of that Tetris remix didn't appeal to me, though. Maybe have a song selection, or something with not as short of a loop.
