@andrew2212,
As others have already said, congrats on your game!
As for tips regarding marketing:
1) start doing it! 
Writing a marketing plan is all good, but until plans turn into actions, they aren’t worth anything. You can do lots of things, the simplest of which are going to other forums, reddit, imgur, game reviewers, etc. and promoting your game. You don’t have anything to lose.
2) I tried to download your game on my iPhone, but I couldn’t find it on the App Store by searching for “Candy Words”. It’s a problem if your potential players can’t find your game even if they directly search for it. You’ll need to perform some app store optimisation. For instance, the only two mentions of “Candy Words” on the Google Play page are the game’s title and one review.

On your website, you state that “All levels and game play are completely free.” and on Google Play page you state that the game is “Completely free!” However, these aren’t true since the game contains IAPs, which means that the entire gameplay cannot be free even if the IAPs are 100% voluntary. Even the term “Free to Play” has come under scrutiny as it isn’t completely accurate.

Finally, this is something of a game development and marketing tip at the same time. Pace out your content. I’m not sure if you created those 900 levels by hand or via some procedural system, either way, that’s some nice work! However, all that nice work might go down the drain unless your game attracts enough players and those players actually reach all the way to level 900. Here’s another advice, implement in game analytics to track how far your players get, how long they spend in certain levels, etc. This way you can tweak your levels if one turns out to be too difficult. Additionally, you’ll know when players are reaching the level cap and when you should create more levels.
I’m sure that many others agree with me that you should aim closer to a minimum viable product and add extra content with future updates. This will save you a lot of work and it works great for marketing. Think about it. Why (and when) do you need to release the next 10 or 20 levels if there are already 900? If the updates are far apart, the game’s profile will decrease on the app stores, whereas frequent updates increase its profile.
For instance, had you released the game with ~200 levels and then released a new content update of ~15 new levels every two weeks, you’d already have updates lined up for the next two years (but again, making the levels beforehand is not a wise investment as you don’t know if people will be playing your game past the level 100, etc). The same applies with multiplayer mode and other features. If you don’t have enough players and the game isn’t originally intended to be a multiplayer title, then is the investment worth it?
ps. I managed to find and test the game on my Android, and for the love of all that is good, let the users control the volume with the Android volume buttons When I have headphones on, I don’t want to wait until the menus to turn down the deafening volume.
