Took me a few seconds to figure out what was going on, and it is a great idea.
But I can't control it. It is WAY too laggy, and I basically got to the point of giving up after a minute because it was IMPOSSIBLE (for me) to understand what is going on in the level with that lag.
I won't rate it because I don't think it's fair of me to do so to a game I technically did not play :P
