Some Awful-Looking Buttons and More Worms

Now the game has a few horribly-drawn buttons for selecting various user interaction tools. I'll make some better-looking icons later. There are also some more worms (which are actually animated now). I've implemented the leftmost button that scatters worms away when the screen is pressed (eventually useful for dodging predators). Through the magic of congruent triangles, worms move to a set radius away from the tap location, without any trig calculations involved. It even uses the cool 3D ripple effect in cocos2D. Screenshot:
