Excellent port. I loved this game way back when. One little hint, as opposed to the on screen instructions, you need to create a file in your home directory called ".moon_lander" with the single configuration line as follows: 3 1 1 1 1
The .moon_lander file settings will allow the use of the arrows on a bluetooth keyboard or the D-pad directional buttons on the N800. I would assume this will also work on the N810 as well.
