I only played this for a little bit before I had to stop, which is unfortunate, as it has some nice elements to it.
This game has your standard breakout/arkanoid mechanics - move the paddle, bounce the ball back and forth until all the blocks are broken. What's a little different with this the ball comes out of your liquid metal reserve in your paddle, meaning the length of the paddle is directly proportional to how many balls you have left. When you run out of liquid metal, you lose a life. There are also three different sizes of balls you can have in play, which change how many bricks you can break before the ball will bounce. As you break the blocks, drops of liquid metal drop down and, if you catch them, they cause your paddle to grow. Catch too much without using it (you can have multiple balls in play), and the paddle will start ejecting the liquid metal all over the place.
...I'm probably making this sound a lot dirtier than it is, but I don't really know how else to describe this without getting really silly.
Anyway, the game has power ups, all of them deal with how the ball destroys the bricks. Some make you punch through them in a line, others take out a large group at once, others shoot off electricity and hit others randomly. Their usefulness can be situational. Finally, there is an area on the stage that, if you get three of your balls into it (it doesn't need to be all in one stage; they seem to carry over), you can create a REAXXION, meaning the balls turn from silver to gold, go from three to five, grow in size, and then shoot out everywhere.
Anyway, while all of that sounds neat (and indeed, it is pretty neat), it has some flaws which made the game unplayable for me. If you're playing in windowed mode, it doesn't take much for the mouse to travel out of window, causing the paddle to stop moving. And if you're playing full screen... it still kind of seem to do that. The other problem is the paddle seemed to stutter quite a bit, which is aggravating when you're trying to bounce the ball back.
So yeah. Good concept, but those issues make it a poor execution.
