If you need constant rewards, endless powerups, crisp vector graphics, achievements, online challenges, multiplayer or 3d.. this is not the game you are looking for. On the other hand, if you love old style, pure of heart out-and-out arcade gaming, you and My Nuclear Octopus may just be on the verge of a beautiful friendship.
Play for a few minutes, get as far as you can, the game ends. Next time, you play again and try to beat your score. Somewhere along the way, the rest of the world disappears and you find yourself one with the Octopus, in some kind of harmony with the game as, for a short time at least, 100% of your focus goes into keeping back the marauders from another dimension.
Lose yourself for a short time, just like we did in the old days.
