Insanely fun game... I've yet to get to the bat though. The dragonflies are great for cleaning up the web, when you eat one just start clicking on every bug you have caught.
Definately hard, but with the colour hot keys you soon get into the flow of things and it is quite fun. Not as bad as some of these comments make it out to be.
Ragdoll physics elevate this game above the usual "avoid falling things" genre. I like when he's in the corner and you tap across towards the wall again and again and it looks like he's leaning against it with one arm and banging his head. Small things. But it amuses me. 400 is a hell of an uphill battle for a badge though...
