Hi Drem (and Thraka)!
Yes, there's still some polishing that could be done ;-). That being said, unless someone can spot some gamestopping bugs, I wouldn't mind it being included in the official repository as it is. The most apparent polishing that is lacking, is the better scaling of the graphics and / or redrawing some of it (the small font is the most obvious candidate). But it doesn't look that bad IMO as it is, it could just be improved.
Aboid FreeDroidRPG: You're absolutely right about FreeDroidRPG - I believe most of the work would involve adapting the UI to 320 x 240, otherwise it should be within the capabilities of the GCW Zero. However adapting the UI might not be that trivial and might involve quite a bit of work. As it is more complex of a game (than FreedroidClassic) it is imperative, that the UI (such as text) is well readable - unlike in FreeDroid Classic, in which it doesn't matter that much if a droid's talking about scratches in paintjob is difficult to read ;-).
Also, I don't know about FreeDroidRPG's other dependencies - there might be some libraries that need to be ported over. It's been a few years since I tried it the last time, and I haven't even looked at it's source either, there might be other issues. It's probable that the UI needs some tweaking here and there. All in all, FreedroidClassic was quite trivial to port, FreedroidRPG will be more work, but probably feasible =).
