Cog 1 helped me to create an amazing game with great UI/UX, which I liked very much! They were always open minded about my ideas even if they had little experience using Unity (which was one challenge we faced).
The project manager did not really know how things should be done but she learned fast as her skills improved along time due their training sessions where taught by experts from big companies like Blizzard or Zynga etc., so it's actually quite normal nowdays having no real knowledge before starting your first job at some startup studio :) Highly recommended!! We worked together during 2 years doing different projects such us : A VR Game called "The Journey" - using both unity3d & cocos2D; An Augmented Reality application named ARCHOS World Vision Project designed around our social platform ; And also designing new features into other games developed previously.
