The game, described as an 'empathy' game, aims to remember the victims of the 2011 Japanese tsunami. Royalties of the game are donated to related charity funds. I really like the concept and intentions for the games profits.
The setting is on the beach, at night, the scene looks pretty and the blue shades fit the mood. It is an experience game/ walking simulater. The player follows around a butterfly, finding various items washed upon the shore. You can inspect the items and then go on to the next. This almost gets repetitive, however, the game is very short, about 15 to 20 minutes. In the end, the short game time balanced out the lack of gameplay variety for me.
Overall, I liked the ideas and setting. The game is short, but also cheap. If you are interesting in the main idea, might as well give it a try.
