I think it's funny that "Save the Universe" is buried somewhere in there even though that's the goal of the game and the rest is just fodder for achievement nuts (OK, disregarding high scores obviously, the real goal of the game). Tellingly, you're also missing wizard mode -- though I suppose you could make that one secret.
Personally I hate achievements of the form "do X 100 times" especially if it's just a matter of time before you do if you continue playing the game, but I do see how it works psychologically for people who care about that sort of thing.
