to correct u QXR2 the proper physics term is current which is the dangerous part of electricity. But you are correct in the fact that it is not voltge.
sorry about the double post, but i have to correct what i just said about a second versian as this is a demo for the full game. as Bomber has said, this is pretty much a full out flash game.
I had some fun on the last level. I found out that if you get over 50 speed upgrade diamonds, the packets move really fast, and if you get over 70.... well I can berally see them, forget keep track of them :)
Anyways, good game, hoping for another version to come out.
