Draw an object and watch it be crushed as you turn up the gravity to 100. Friction and collisions between objects have not yet been implemented. Press "P" to pause and enter editor mode. In editor mode: Key "D" to delete the item under the cursor, "R" to delete all. "F" to toggle drawing (adjust properties of the next object to be drawn, or draw). Click and drag to draw objects. If an endpoint is drawn above an existing endpoint, they will automatically connect.
