Meiji Tweet Fantasy Game‏

This is not easy to completely figure out. Meiji Fruit Juice Gumi is sponsoring a Twitter event where people tweet to help complete an online story or game. The characters in the game need people's help in order to progress to different stages. The instructions also explain that tweets can be used to create boats and other items in the virtual world. I am not much into such things, but it does appear pretty elaborate for a product promotion.

The characters' names are Megumi and Taiyo (メグミとタイヨウ), both of which relate to the product (the gumi of Megumi and Taiyo means sun and is thus related to fruit). The game is called Tweet Fantasy or Time Line World (タイムラインワールド) and since I cannot see other mentions of it online, I have to conclude that it is not a cross promotion, with a game for example, and was actually developed for this promotion.
