I'm currently participating in the LudumDare 48 hour game programming competition (create everything from scratch in 48 horus).
Right now its playable (still needs some polish), but I'm wondering if I can have some comments/criticism as to whether or not its fun, confusing, etc.

The Plot: "A launch signal is getting sent to a USSR ICBM, can you stop it?"
Fly around, and blow up the batteries to disrupt things so that the electrons cannot start the launch sequence.
Edit:
Batteries come back eventually (after you've killed them).
If you kill a battery, any electron that was between it and another battery dies.
