Simple d-pad with WASD and overlapping. I haven't tried to mess with the other options tho, I find this one good enough.
I've uploaded the config as "Kharnete bindings". You may want to change the touch menu position or size, I'm just used to have it there. Also, I can't remember if on the end game we would need more than 7 buttons on it, but that's something easy to fix.
Thanks, I'll try it out the next time I'm playing.
