For me it's working fine. Good job!

I have a N900 with english keyboard.

I use arrows keys to move, "." and "enter" to strafe left and right, "a" and "z" to look up and down, "shift" to fire, "alter function" to do an action and "m" for the minimap.

I have a problem. Once I launch the game I can't go back to the menu. How can I do? Thank you in advance!
