- none. Really?

### HISTORY
- Original game differences
    [] each kind of alien is scored differently (30 - top row, 20 - 2xmiddle rows, 10 - 2xfor lowest rows)
    [] each row is moving independently, slightly ahead the row above
    [] after destroying alien, there a short sprite swap for blast image
    [] player's and alien's shot can destroy each other when met
