Hi cupcake, Brutal Doom should work on the latest version of the app. As far as keyboard and mouse support, keyboard is supported currently but I'm not too sure about how difficult it would be to add in mouse-look.
Hello, I've recently released a bundle of Freedoom and an open source port of GZDoom for android on the play store here. I was wondering: A. Is ok for me to keep it there? B. Can I keep using the freedoom name for the app or should I try and change it to something else? C. Is anyone interested in this kind of thing, possible other bundles with community wads, or helping out with improvement? Github link: https://github.com/mkrupczak3/GZDoom-Android
