The lack of an online leaderboard proud of your skills are at a disadvantage. What fun marking a lot, if you spread the word among others? Space Invaders was very challenging, but it does not change the tone quickly.
It is important to note that there is a place where the Space Invaders has not changed even a bit. The graphics and sound department is almost the same as used in the arcade version. Except for the option to blow by colorful aliens and modern background, all things being equal. If you're hoping to scare your girlfriend with alien, you are in for a disappointment. The aliens looked like crabs and bats and not even remotely scary. If you play the game, and the bleep bloop sound will bring fond memories.
