The part I really enjoyed was when Phil was staring into that old program like when he was a kid. I think we all did stuff like that, it was cute and honest. Phil wears his heart on his sleeve for good or ill. I don't know much about what happened recently so I can't speak to that or have any opinion, but I do think he is very talented. He takes everyone's thoughts about him to heart which can make him better at what he does but also it contributes to his bitter view on the world, which in turn...doesn't help matters. Again, not knowing much about anything other than my own observations, I would suggest that he;
A.) Be open to criticism and
B.) Pick trusted individuals or mature groups to tell him the truth
Criticism and being able to handle criticism is essential for any creative person to succeed. It fucking sucks, but them's the breaks. If he lets everything in from every knob on the internet, it's a road to absolutely nowhere.
Aside from that I got super emotional during the backstory segments for Edmund McMillen. I'm really happy for him and his partner. All around I love Indie Game: The Movie. I hope there are more as the years go on and the indie scene evolves.
