I played the previous game quite the bit and liked it alot. With the adition of graphics and achivements to enhance the gameplay i makes it even better.
I just unlcoked the locust, and i would like to see it actually standing on the groud as it doesn't have any wings. And as we get ridiculous amounts of earlier creatures it might be cool to get a sense of the amount you have by the graphics showing more of that type of creature in the backgroud.
