I uploaded some gameplay video of LetterWriter: Oceans last night to YouTube. You can get an idea of what the game looks like and how it plays.
In the clip, you get to see several of the features:
• The panorama where you select the letter to practice.
• Several of the letter backgrounds.
• The earning of starfish as you complete letters.
• Earning four starfish unlocking the storybook.
• The options screen.
