sorry for double, but I'm not done.
What the group of juvenile elephants was doing resembled what gangs do. And the solution the park had for it was to add more adult elephants. When the adult elephants were added the killing completely stopped. Elephants are a highly intelligent species that deserves our respect, so I support your message jmtb02.
This reminds me of a show I had watched a while ago. It had suggested that it is possible for elephants to get Post-Traumatic Stress Disorder. Which would be common among them because often times baby elephants see their own parents killed from culling. Another thing the show had shown that supported Advanced form of intelligence in elephants was that, in one part the show talked about how in one scenario, a group of juvenile elephants were killing random rhinos for no reason at all.
p.s.s. also some clear in-game instructions. sorry for triple posting, but I think your game has lots of potential and I want to see that potential reached.
p.s. you should also add different difficulties because it seems a lot of people rate this low because it is hard. And add highscores for how many of whateverthoseares you can get across your bridge.
You should try to improve this a bit more by adding levels, some whuch would have bigger heavier monster guys, maybe one could have to go over a hill, or underwater. If you expanded this and gave it some story and background it could even get a badge. it could be more than just bridges even. maybe towers or mine shafts that have to support the wight of the tunnel. I think I've ranted enough for now.
