It took as long as needed. You should be super proud. Completing a big project is a real milestone which no one can take away from you. You're probably a bit exhausted and busy launching/patching but don't forget to take a moment and savour that victory. Completion, as you know, is hard!
Also: the game is great, and from what I can see people are enjoying it, so that's a whole extra level of success! It's important to absorb and savour the successes as they are important.
Good luck with your sales! Well done!
