The developer has ruined this and turned it into a dismal flop of a game.
A lack of updates does not 'ruin' the game - what exists does not change. It just means the people who wanted more are dissatisfied and start whining in the comments section. *shrugs*
If you want to say it ruins anything - it'd be the dev's chance to make money from his game since a good portion of his target audience will have started ignoring the game title if he really does release a big update later.
