I give this level 5 stars, though after reading the forum am not sure, anymore, what this stars are for or what they are meant to mean, so I just wanna say, that coming from me, they don't have as much to do with how difficult I find a certain level, or how much time I spent on it, but it has more to do with how much I enjoyed it (for different reasons).
For example, here, I spent about 10 - 15 minutes, it made me think, because the first few tries showed very wrong. Then I soon came closer, but still had troubles with getting rid of the last two moves.
So, I find this a great level.
