I have to say, it's incredibly fun to be a WMD: worm of mass destruction!
Especially in sandbox mode when you can get your worm to be literally bigger than the screen. This game doesn't really have much challenge to it, but I love that beauty with this one: you're just out to munch some helpless victims and have a bangin' good time with it. And for that, this game excels.
I loved the first one, and I love this one even more (having the wings as a default ability was a good decision, I think). 5 stars!
