It's a pain to keep getting attacked by weaklings that don't stand a chance against me. If they can't hurt, they shouldn't fight! It just makes travel annoying.
Interesting game, but badly broken. The biggest annoyance for me is how quickly the elephant moves backward... faster than all of the obstacles, which means the geese, for example, are flying BACKWARD. Since it's a flash game and you don't have very fine control, it's too hard to watch what's behind you all the time and stay ahead of it.
Clicking lights is terribly broken for me. Macbook w/ Firefox 3. I click, and it acts like I clicked wherever my mouse was the LAST time I clicked. Or something. It's impossible to use.
One of the best games I've seen in a long time. It would be nice if it wasn't so easy to reduce pollution; it's a much bigger problem in the real world than it's shown here.
