yeah adding visuals to let you know which player you were controlling was on my list, I just didn't have enough time to implement it like with many things. Now seeing criticism and watching my friend attempt to play through it I know this game would fare much better with less precise, more puzzle / problem solving type platforming. The reason you have to find a triangle with the same rotation and opposite colour is because it was the triangle listed inside the bodies of both circles, (you would have to get each to their own goal) and the different colour because you cant phase through objects of your own colour, only the opposite. Though I agree that it may be a little too complicated.
thank you for the criticism!
