Using the 3 grids for a mapping as I described didn't work but it was down the right path. I searched for an alternate mapping and finally found one (even simpler) that worked. My comment about there being no '9d' is a BIG hint though as it applies to the right mapping too (using 4pollo's notation).
Also, in my search I ended up going through all the possibilities for some dot positions. 5 squares seemed either ambiguous or a complete unknown so I just ran through all combinations. I can say that the majority of 4pollo's grid is correct.

I still don't know how to find the mapping from the symbols to the alphabet. I tried forming grids from QWERTY and AZERTY keypads (just as Coinnoiseur sugested), but didn't suceed. One of the mapping that I tried is:
Q W E
A S D
Z X C
R T Y
F G H
V B N
U I O
J K L
M P
mirth23 mentioned that the URL to the text game has some hint, but I haven't discovered anything. Any advice?
