Flash Physics Game
I wanted to post this game a few weeks ago, but it was a little unstable and had a tendency to crash some browsers. This version appears to be much more stable, at least for me so I feel comfortable posting about it to share with you.
Anyways, Cargo Bridge is a bridge building game where you have to build a stable bridge to get to crates, chests (and even elephants) and return them to the storage facility. You have a limited budget on each stage and the cheaper you can build your bridges, the better. You have to be careful not to make walkways too steep or the workers won't be able to push the objects up them. The first fifteen or so levels aren't too difficult, but after that, the levels seem to really test your engineering capabilities. if you get stuck, you could probably find a solution on Youtube.
