considering that we know that the games are probably linked it is possible that the letters that you get while playing "dont play this game" can be used in "the painful box"
I tried, but after you click the letter you have to choose a number...
posted a video already about it not far up. it does add in the Painful box. just watch it
could you send a link to it?
