Aside from the text and menus, the game is actually playable, despite the crabs.  In fact, the areas and most of the enemies are still easily recognizable to anyone who has played the game.  However, comments on YouTube have many complaints about getting headaches from watching the video, so you might want to hold off on doing it yourself.  

For an extra dose of irony, guess what enemy is featured at the very end of the video?  The giant swamp crab, who still proves to be a little too strong for the player.
