Soon to submit to App Store!

Finally, the Kanji Wordsearch app seems about ready to submit to the app store! It's taken a lot of time with many twists and turns to the development process, but I'm happy with how it has turned out. Now, to let people know about it - I've got to make a video for YouTube, a Facebook page, app reviews, contact Japanese learning sites etc. Any other ideas about how to avoid this sinking into oblivion in the overcrowded app store?
