Kongregate Achievement Help

As a veteran of the website I have referred you all to in another topic, Kongregate.com has achievements ranging from the easy to the absurdly difficult. I have completed a lot of them and the ones that I havn't completed I know how to complete, I just havnt got round to doing it or I dont like the game. Anyway, I have set up this topic so you can request help on how to do various achievements that you cannot do and I will try to come up with a strategy that works.

Although please don't ask about the Impossible achievement on Desktop Tower Defence 1.5, I dont think anyone can do that =D.
