Ultimate 2D Physics 2.11
Press space to spawn a new polygon.
Click on nodes to "freeze" them, click and drag to move them. Click and drag elsewhere to create a force.
Click on stage to add a new node. Click on existing nodes to select them: select 2 to create a link between them.
To delete a node, click on it. Any links to the node will be erased as well.
Trying to get things working again... -_-
