I can see why this game is remembered. I can see why it and its kind were influential. It's a good thing I wasn't playing it in an actual arcade, because I can imagine losing a large number of quarters to its clutches. It speaks of a time when those tiny purchases, or micro-transactions, made up a massive amount of the revenue a game could bring. It uses the small iteration time, and tries to perfect the feeling of "Aw, I nearly had it." Difficulty is low and the play simple but spikes suddenly around unique sprites and scheduled set piece moments.
