I don't see what is so difficult about this game.
21 took me 5 minutes tops, without the walkthrough. There's a method to all of the levels, really. 17 is a challenge to how quickly you can click. A bunch are precise, aiming levels, and others are just common sense.
If 21 is annoying you, then I suggest trapping a small group in a corner, and work from there. If you protect the small group, then before long it will be a large group. Just try to keep them contained, and you should have it.
4/5, could use some more levels.
Great game... After completion, I'd find it hard to believe that you weren't high for the extent of making this.
Oh, and what the hell was up with the evil laughter at points in the game? :P Especially at the end.
I'm getting good at this game- my intense OCD habits are helping me out here... DO EVERYTHING EVENLY ON EACH SIDE! =P not poking fun, I really am a moderate OCD.
