The game was complete since its release anon. You have an ending which is a nice conclusion to the story, but you have the option to mess around as long as you like with any side tasks before the ending scene in the island. The updates are genuinely extra stuff being added. The last one got new CGs to one of the side characters you can romance, and the previous to that one added a new quest with its own boss, a new character, and more CGs you can access if you complete it. So if you finish it now all you need is a single save before the ending and you can play all new stuff freely without troubles.
