Aidan
The mouse isn't at the same place the hand is, so you have to look at where the mouse is for where to grab things even though it should be the hand. I also got a bug with putting the pipe in Aidan's hand and taking it that caused the pipe to vanish entirely. It's a cool idea though, all though so far controlling Aidan hasn't really mattered. Maybe put in like a pressure plate thing where Aidan has to be in a certain place or something, or some other puzzle where it involves a physical thing, otherwise you're just controlling the imaginary friend the whole time.
It's a cool idea, I like the art, and I look forward to seeing the full thing.
