The idea is great: breakout with more realistic physics. The first few levels, its really fun. But then the level design gets progressively more random, where the player has to just wait for the level to "decide" to let you win.
One level has five widely roaming portals, all which randomly link to each other. You just watch and wait to see if the ball is ever coming back; its like playing a slot machine. And thats not what this kind of game is supposed to be. The "random" just gets worse as you go, as a way of difficulty I suppose. More and more waiting for the level to let you win.
Good idea, bad design. (Also, seriously burns through my battery on a 5S. No stars docked for that, but buyer beware.)
