I had the change a couple of line to make it work because term.everything takes input only from stdin (this way it works of ssh and is pretty broadly compatible across terminals).
1. I had to remap another key to the control key (which is usually used to send signals like sigterm)
2. Then I had to change the timeout in which keys are pressed. When using stdin, you get a keydown event, but you don't get a key up event (ever). So I have to guess when you want to key up. Most of the time, I can send key up right away. But, it looks like doom has some sort of key debounce, so I had to wait 50-100 ms for keyup. Then there is the problem of if you want to walk forward in games you usually hold down up arrow, but now you have to rapidly press it! Not ideal, but it does work, and it it playable.
