Walking into an amusement arcade during the 1980's overwhelmed your senses. The audio from every arcade machines screamed out for attention, each one fighting to grab the passer by, begging for you to feed it with coins.
My Nuclear Octopus is what might have happened had I been born a few years earlier and landed a job designing arcade games in 1984. It's loud, it's simple to pick up and it's tough as old badgers. The graphics are crunchy old sprites, something you might see in an old Commodore 64 game, a BBC Micro game or maybe even a 1980's arcade.
The logic is simple - you play for a few minutes, you 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.
