This blue dot is a crazy one. Why it doesn't want to play with other dots? The blue one would like to escape this world of clueless yellow dots and disappear forever. We don't know the reasons for sure, but we can just guess... Whatever. If it feels alone being blue, it's its own fight. Your job is to don't let it slip away, though. You are here to keep these guys together and work on their relationships. Prevent the blue dot from escaping by blocking its path in correct way. Have fun.
