iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii.txt is a file created during Act 2 after the second iteration of the poem game. It reads as follows:
I hate this. I CAN'T DO ANYTHING. NOTHING. No matter how many times you play. It's all the same. It would be really, really easy to kill myself right now. But that would mean I don't get to talk to you anymore. All I want is for you to hate them. Why is that so hard?
