Developed by a group of college friends for a class project, the title began garnering some attention after their teacher (Osmos developer Andy Nealen) encouraged them to show it off. After bringing it to events like the Independent Games Festival it began winning awards, and getting all the right kinds of attention. Eventually Ubisoft became interested enough to offer the team a spot on Xbox Live. All they would have to do is deliver.
