Work it up
Basically all you got going for you is a new and original concept of balancing. but right now your game is flat and boring.
First of all, try imaging your favorite game, be it bio shock, call of duty, or barbie pony riding, reduced to 15 second play periods of the same level over and over. You wouldn't play that game for longer than a minute. Try variations not only in the appearance of your levels but also in the style of game play. Add obstacles to get past, enemies to shoot at, or different rope materials with different effects. I don't know what, but figure it out.
Also, your game has almost no psychological pull, there's barely any reason for the player to want to continue playing after he plays one level. Try adding items or achievements or unlockable; you need a way to interest the player and engage them in a desire to play and play and play.
I reviewed this because you have a great concept with the whole balancing thing. If you could take that idea and turn it into a worthwhile game it would be both successful and original.
