Hah, this is fun. Thanks!

I can't deal with the dpad-enter as firebutton though.

On n810, it would be best to have return and backspace be fire and superbomb (or some other key on the right)

On 770/N800 i think two onscreen buttons on the right would be best. To see a simple onscreen button with source code, download http://pupnik.de/aliens-1.0.2_Nokia.tgz
