- position of the mouse determines the height of structure [press Q to start while your mouse is in the black area]
- each slider controls the number of branching for each level [don't forget too many branches will be problematic]
- [with reasonable number of levels and branching] press Q/W/E/R/T for different load conditions
- hold down the left mouse button while pressing Q/W/E/R/T for additional horizontal springs
- if your structure is failing try to decrease the number of levels or branches you're trying to create
