We could have different elements spawned with spray cans, they would be "Dots" made out of particles that would assume the properties of the element.
Bricks would serve as "wall".
This could make : Bombs.
Power system, using electricity idea from powder toy.
Chemistry
All you can do in powder games, except,
Stuff having to do with pressure and wind. Well, atleast so that would not effect the player.
Maybe like brick physics, where its client side. Except for electric currents, which would probably have to be bound to events to make power systems.
