Heyo ~
I thought that the game and the execution was very creative, I loved the meta jokes packed in here and can relate to them for sure.
One issue that I ran into was that it wasn't immediately obvious what I was supposed to click/do in some of the scenes. I think that clickable and intractable things could definitely do with some visual highlighting. I also noticed that when dragging the files in the mouse position wasn't correct. I believe this might be because it's not taking into account variable screen sizes properly and so the drag position is reported wrongly.
I had a lot of fun playing this and thought it was really cool. (A game about developing in unity made in unity :O). Well done :)
