for movement change to keyboard and mouse controls to move and look around
it's too limited for moving
if I had to play a 3d shooter game like this I would stop playing it
the closest examples are WolfInstine 3d a very old dos game
I've been playing 3d shooter games on the pc for many years
Like since 1997
I have game Ideas and would never put that limited type of control in
ya I know it takes a bit to get use to
but I think are limiting what folks would
be able to work with by having it the way it is now
I remember in Duke Nukem 3d
there was the option in the game to give the player
the choice to chose which way they wanted to have the controls
so my thought to you is put that in your program and
let the player chose which one they want to use
