Hi, I found a way to run nethack on my old Kindle that many people actively use nowadays.

But after some time playing with the PW1, the controls to move the character became not much intuitive.
So after a research, I found Nethack for Android. There is a fixed directional and a row of most useful commands and some adaptations, like the option to kick a door when it's locked, automating the need to ctrl+d or k and choose direction.

I tried to bring to kindle but with no success, with some luck someone can bring this improvement to us.
I use this forum a lot of years, but only now there were the need to contribute, so thank you for all people that bring help, specially the developers!
